Geometry

This chapter explains the altitude of a triangle and its construction, median of a triangle and how to draw medians of a triangle. It also mentions special points of a triangle, such as the point of concurrence, centroid and orthocentre.

This chapter discusses the areas of trapezium, parallelogram, circle, trapezium, rhombus, and triangle using Heron's formula. The area of figures having irregular shapes is also discussed here.

In this chapter, we will study the properties of the chord of a circle, arcs corresponding to the arc of the circle, and finding the length of the radius when the chord is given. Finding the distance of the chord from the centre is also explained.

This chapter describes the congruence of a plane figure. It also teaches us the congruence among line segments, besides the congruence of the angles.

This chapter explains the properties of parallel lines and transversals. Angles made by the transversal, transversal of parallel lines are described. It also teaches how to draw a line parallel to the given line through a point.

In this chapter, you will study quadrilaterals and types of quadrilaterals. You will also learn about the properties of trapezium, kite, rectangle, rhombus, and a parallelogram.

This chapter describes the terms related to a cone and gives the formula to find surface area and volume. It also explains the surface area of a sphere and includes some solved examples to explain the application of these formulas.
