Perimeter
This document provides a lesson on calculating the perimeters of polygons. It begins by defining a polygon and perimeter. Students are shown how to calculate the perimeter of a rectangle by adding the length and width measurements. The formula for a rectangle's perimeter, 2 x length + 2 x width, is introduced. Other shapes where not all side measurements are needed, like squares, are discussed. Finally, students are given a challenge to calculate the perimeter of a more complex shape and express it in words and letters.
Visualizing the area of rectangle

Triangles educational video for kids.mp4
This document provides information about triangles, including:
1. It defines a triangle as a geometric shape with three sides and three angles.
2. It lists the three main parts of a triangle as the sides, corners (vertices), and angles.
3. It describes the three types of triangles - scalene (unequal sides and angles), isosceles (at least two equal sides and two equal angles), and equilateral (three equal sides and equal angles).
Calculating Perimeter
This document discusses measuring the perimeter of shapes. The perimeter is the distance around a shape. It is found by adding up all the length and breadth measurements of the sides. For a rectangle, the perimeter can be expressed as "twice the length plus twice the breadth" or written as 2 x l + 2 x b. Other shapes like squares also have a simple formula to calculate the perimeter without measuring every individual side.
2 Dimensional Shapes
The document provides instructions on drawing triangles and identifying different types of quadrilaterals. It explains how to construct an accurate triangle using a ruler and compass by drawing three arcs from the endpoints of a base line. It then lists seven types of quadrilaterals and provides the formulas for calculating the area of triangles, parallelograms, and trapezoids.
Sec. 10.1
The document discusses calculating the area of parallelograms. It defines key terms like base, height, and perpendicular. While rectangles have four right angles, parallelograms only have two sets of parallel sides. To find the area of a parallelogram, multiply the base by the height. The height must be drawn perpendicular to the base. Examples are provided to demonstrate calculating areas given the base, height, or area.
Perimeter
The document discusses perimeter and how to calculate it for different shapes. It defines perimeter as the distance around a shape and provides formulas to calculate perimeter for rectangles and polygons. For rectangles, the perimeter formula is P=2l+2w, where l is the length and w is the width. For polygons, you add up the lengths of all the sides. The document also shows how to use algebra to solve for missing side lengths when given the perimeter.
Polygons
The document discusses different formulas for calculating the area of polygons like rectangles, parallelograms, triangles, and trapezoids. It explains that the area of a rectangle can be found by multiplying its length by its width. The area of a parallelogram is the same as the original rectangle since only the shape changed, not the area. For a trapezoid, the average of the two base lengths is multiplied by the height. For a triangle, the area formula is one half the base times the height since a triangle is half of a parallelogram.

The document also includes examples of drawing squares based on the sides of a right triangle and using the theorem to solve for missing side lengths.

It begins by defining fractals as shapes made of parts that are copies of the whole, with theoretically infinite detail and self-similarity regardless of scale. Examples given include the Sierpinski gasket, Koch curve, and fractal trees. Fractals can have infinite perimeter but finite area. The concept of fractal dimensions is introduced, where fractal objects have non-integer dimensions. Chaos games and the Mandelbrot set are discussed as examples of chaos theory and fractals found in nature. Benoit Mandelbrot is credited with bringing fractals and their ability to model irregular natural forms to the mainstream.

It then provides examples of how to calculate the area and perimeter of irregular figures by boxing the object and using the length and width of the box. The area of an irregular figure is the area of its box minus any empty space within the box. The perimeter of a figure may be the same as the perimeter of its box, but sometimes the individual sides must be counted and added to find the perimeter.
Instructional Materials in Mathematics
These are the instructional materials/manipulative that I made in our Instrumentation in Mathematics class.
Geometry
Euclid was known as the "Father of Geometry" and wrote the influential book Elements about geometry. The ancient Egyptians built pyramids and the shapes included in geometry are polygons, cubes, pyramids, prisms, cylinders and cones. To find the perimeter of a shape you add up the lengths of all the sides, and to find the area you multiply length by width, or use formulas like 1/2 base times height for triangles. Volume is found by multiplying length times width times height. Nets are unfolded 3D shapes.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
