Plane shapes
The document defines and classifies different plane shapes including polygons, triangles, quadrilaterals, and regular polygons. It discusses the key characteristics of these shapes such as the number of sides, angles, and parallel or equal sides. Specific shapes are defined, such as triangles being classified by angles (acute, right, or obtuse) and sides (equilateral, isosceles, or scalene). Quadrilaterals are classified as parallelograms, rectangles, rhombuses, trapezoids, or trapezoids. Regular polygons are those with all equal sides and angles.
Quadrilaterals
This document presents a summary of quadrilaterals for a class of 9th grade students. It defines a quadrilateral as a four-sided polygon and discusses the key components such as vertices, sides, angles, and diagonals. It then explains different types of quadrilaterals like parallelograms, rectangles, squares, rhombi, trapezoids, and kites. The properties of parallelograms, rectangles, rhombi, and squares are outlined. The document concludes by listing the student team members who created the presentation.
Plane figures

A polygon is a closed, two-dimensional shape formed by three or more straight line segments that connect end to end. Polygons can be classified as either convex or concave based on whether any interior points are contained within lines drawn along its sides. Common types of polygons include triangles, squares, rectangles, and circles, each with their own formulas to calculate perimeter, circumference, or area.
Basic concept of geometry
This is very helpful for new learner.
read and enjoy geometry content.
I hope u will learn a lot from this.
Polygons
Polygons are plane figures bounded by three or more straight sides that meet at vertices. Polygons are classified as convex or concave based on whether a line segment between two interior points crosses two or more sides. They are also classified by the number of sides, with triangles having three sides, quadrilateral four sides, and so on. Regular polygons are both equilateral and equiangular. The interior angles of a triangle sum to 180 degrees, while the interior angles of a quadrilateral sum to 360 degrees.

Polygons
This document defines key properties and attributes of polygons. It explains that a polygon is a closed figure formed by at least 3 non-intersecting line segments, with sides connecting vertices. A regular polygon is both equilateral and equiangular, while an irregular polygon is not. The interior angles of a convex polygon sum to (n-2)180 degrees, and the exterior angles sum to 360 degrees. Examples are provided to illustrate how to use these properties to calculate angle measures.
Maths
This document discusses different types of quadrilaterals. It defines polygons and quadrilaterals, and explains their properties. Some key quadrilaterals discussed include parallelograms, rectangles, squares, rhombi, and trapezoids. The document explains that parallelograms have opposite sides of equal length and opposite angles of equal measure. It further notes that rectangles are parallelograms with four right angles, while squares are rectangles with all four equal sides. The properties of diagonals and angles are also summarized for various quadrilaterals.

This document provides teaching and learning resources on geometrical constructions. It defines various 2D shapes like polygons, regular polygons, and irregular polygons. It lists the names of polygons according to the number of sides. It also describes 3D solids like cubes, cylinders, prisms, and pyramids. For cubes and cylinders, it provides the formulas to calculate their volume and surface area. It includes examples and diagrams of different types of prisms and pyramids. The resources were prepared by a group consisting of Vanesri Kasi, Yamuna Sandaran, and Tinagaran Magesparan for computer construction.
Structure Geometry
This document discusses different types of geological structures and methods for representing their orientation in three dimensions. Planar structures include bedding planes and fault planes, while linear structures include folds and faults. The orientation of structures can be described using their azimuth, dip, and relationships to coordinate systems. Different projection methods are used to depict structures, including perspective, orthographic, and stereographic projections. Stereographic projection maps planar and linear geological features onto a sphere that is then projected onto a plane.
Understanding quadrilaterals chapter3 grade 8 cbse
This document defines and classifies polygons and quadrilaterals. It begins by defining curves and polygons, with polygons being plane figures bounded by three or more straight sides that meet at vertices. It then discusses the parts of polygons including vertices, sides, consecutive sides, and diagonals. Polygons are classified as convex or concave. Specific types of polygons are defined based on their number of sides. The document also discusses regular polygons, interior angles, and formulas for calculating polygon properties. Finally, it defines and provides properties of different types of quadrilaterals including rectangles, rhombi, squares, parallelograms, trapezoids, kites, and trapezoids.
What's Your Angle?
Angles are formed whenever two rays share a common endpoint. An angle can be named using the vertex point and the endpoints of the rays. There are four main types of angles: acute, obtuse, right, and straight. When lines intersect, different pairs of angles are formed including corresponding angles, alternate angles, and interior angles. Corresponding angles and alternate angles that are formed by parallel lines intersected by a transversal are congruent. The measures of interior angles on the same side of the transversal sum to 180 degrees.

This document defines angles and describes how to measure, construct, classify, and bisect angles. It contains the following key points:
1. An angle is the amount of turn between two lines that meet at a common endpoint called the vertex. Angles are measured in degrees using a protractor.
2. To construct a 45 degree angle, mark the 45 degree mark on a protractor and draw a line from the vertex to this mark.
3. There are different types of angles including complete angles of 360 degrees and relationships between consecutive, adjacent, and inverse angles.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
