KSEEB Solutions for Class 8 Maths Chapter 6 Theorems on Triangles

Share

In Chapter 6 of KSEEB Class 8 Maths textbook Theorems on Triangles, you will study about theorems on triangles. Recall from the previous classes that there are three types of triangles based on their measure of interior angles- acute-angled, obtuse-angled, and right-angled. 

In an acute-angled triangle, each interior angle is less than 90 degrees. The obtuse-angled triangle contains interior angles; the measure of each angle is more than 90 degrees. A right-angled triangle contains interior angles; each angle is 90 degrees in measure. 

Based on the length of the sides, there are three different types of triangles which are scalene, isosceles, and equilateral. In a scalene triangle, none of the sides is equal in length. In an isosceles triangle, two sides of a triangle are equal. A triangle is said to be equilateral if all its sides are equal in measurement. 

As we have revised the basic concepts, let us now proceed with the list of triangle theorems that you will study in Chapter-6 of KSEEB Solutions for Class 8 Maths.

In this chapter, you will study three theorems that revolve around triangles. 

Theorem 1: The measure of the sum of three interior angles of a triangle is 180 degrees. 

Theorem 2: In an isosceles triangle, the base angles are congruent. 

Theorem 3: An exterior angle of a triangle has an equal measure to that of the sum of its corresponding interior angles.
