Mathematics

Angles

This chapter describes the components and naming of angles. It explains how to use the protractor in measuring angles and also includes steps to draw angles of a given measure. Further, it introduces parallel and perpendicular lines.

This topic covers concepts such as practical geometry, elementary tools of practical geometry, tips to use elementary tools of practical geometry, methods for constructions of geometrical figures, etc.

Tools used in Geometry

This topic covers concepts such as comparison of angles in a shape, angle formed by two rays, supplementary angles, arms or sides of angles, and vertex of angles.

Angles and its Types

This topic covers concepts such as construction of perpendicular bisector using ruler and compasses, constructing angles of given measure using protractor, constructing copies of angles of unknown measures using compass, etc.

This chapter explains various types of three-dimensional shapes. It includes the concepts of a prism, pyramid, sphere, cone, and cylinder. Properties of three-dimensional shapes are mentioned here.

Three Dimensional Shapes

This chapter discusses the construction of the triangle if the lengths of the three sides are given. It also explains the property of the angle bisectors of a triangle, congruence of angles and bisector of an angle.

Geometrical Constructions

This chapter discusses the properties of the rectangle, rhombus, and square. It includes a test to check if the given figure is a parallelogram or not explores the theorem of mid-points of two sides of a triangle

Quadrilaterals

This chapter discusses triangles. It explains in detail the types of the triangles, such as scalene, equilateral, and isosceles triangles, and triangles' properties based on sides and angles. The angle sum property of a triangle is also discussed.

Triangles and their Properties

Symmetrical objects or shapes have two halves of the same size and shape. In this chapter, we will learn about the concept of symmetry. We will also study the concept of closed and open figures.

Symmetry

This chapter focuses on the concepts related to a line segment. It defines the coordinates, distance, and midpoint of the line segment. It covers the properties of congruent line segments and explores the conditional statements with their converse.
