A triangle can be formed by joining three points. There are different types of triangles like an isosceles triangle where two sides are equal, an equilateral triangle where all the sides are equal. In this chapter, you will study the congruent triangle. Congruence of Triangle means when the two triangles are having the same side and interior angle. In this chapter, students will be asked to prove the congruence of any two triangles. Students will be studying various theorems, using which, students will be able to prove the congruence of triangles.
