POLYGON AND IT'S TYPES
A polygon is a closed shape made of line segments where each line segment intersects exactly two others. The document defines different types of polygons such as triangles, quadrilaterals, pentagons, hexagons, etc. and provides characteristics of each such as the number of sides, properties of side lengths and angles, and the total sum of interior angles. Regular polygons are those with equal side lengths and interior angles, while irregular polygons do not have these properties.

TYPES OF SHAPES
This document defines and describes various two-dimensional and three-dimensional shapes. It explains key properties such as the number of dimensions, faces, edges, vertices and whether shapes have parallel or perpendicular sides. Specific shapes defined include cubes, spheres, cones, cylinders and pyramids. Plane shapes such as polygons, quadrilaterals, rectangles and triangles are also explained.
INTRODUCING TO TYPES OF SHAPES
This document defines and describes various two-dimensional and three-dimensional shapes. It explains key properties such as the number of dimensions, faces, edges, vertices and whether shapes have parallel or perpendicular sides. Specific shapes defined include cubes, spheres, cones, cylinders and pyramids. Plane shapes such as polygons, quadrilaterals, rectangles and triangles are also explained.
Prism powerpoint
A prism is a solid object that has two identical and parallel flat ends called bases, and has the same cross-sectional shape along its entire length. A cross-section is the shape made when cutting straight across an object. Prisms can have different cross-sectional shapes including triangles, rectangles, or other polygons. They are defined as having two identical, parallel bases connected by rectangular or polygonal faces.
Geometry In The Real World
This document defines and describes various geometric shapes and terms that are commonly used in geometry and appear in the real world, including points, lines, planes, angles, triangles, quadrilaterals, circles, cylinders, spheres, and pyramids. It provides brief definitions and key properties for each shape.
Classify polygons
This document defines and classifies different types of polygons. It begins by defining a polygon as a closed figure formed by line segments that intersect only at endpoints. Polygons are then classified as convex, concave, regular, or irregular based on their angles and sides. Specific polygons are also named based on the number of sides, such as triangles having 3 sides, quadrilaterals having 4 sides, etc. Regular polygons are defined as having all congruent sides and angles. The document also provides formulas for calculating the area of regular polygons based on their number of sides and apothem length. Triangles and quadrilaterals are further classified based on side lengths and angle measures.
Shapes
This document defines and describes various two-dimensional and three-dimensional shapes. It discusses properties such as faces, edges, vertices, parallel and perpendicular lines. Specific shapes covered include cubes, cuboids, spheres, hemispheres, cones, cylinders, pyramids, prisms and various plane shapes such as polygons, quadrilaterals, rectangles, kites, rhombuses, trapezoids, pentagons and hexagons.

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
Remote Sensing and Geographic Information Systems

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.

Temple of Asclepius in Thrace. Excavation results
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).
