Did You Know?

The Class 9th Maths Chapter 7 Exercise 7.4 teaches about the rule of congruence and similarity. The rule of congruence states that if two triangles are exact replica of each other and are similar in size, these are congruent. If two triangles have all sides in proportion and have congruent angles then both are considered similar.
