Key Concepts and Definitions:
- Line Segment: A part of a line that has two endpoints.
- Angle: Formed by two rays with a common endpoint called the vertex.
- Types of Angles: Acute, right, obtuse, and straight angles.
- Triangles: Classified by their sides (equilateral, isosceles, scalene) and angles (acute-angled, right-angled, obtuse-angled).
- Quadrilaterals: Includes shapes like squares, rectangles, parallelograms, and trapeziums.
- Circles: Understanding terms like radius, diameter, circumference, and the properties of circles.
- Polygons: Closed figures with three or more sides, classified based on the number of sides (pentagon, hexagon, etc.).
