Congruence Of Triangles

Ex 7.2 | Question 8

## Text Solution

**What is known?**

Two triangles that have five pairs of congruent parts.

**What is unknown?**

Despite having five pairs of congruent parts, the triangles are not congruent

**Steps:**

In triangle \(PQR\) and \(ABC\)

\begin{align}\overline{PQ}\text{ }&=\text{ }\overline{BC}\qquad\rm(Given)\\\overline{QR}\text{ }&=\text{ }\overline{AC}\qquad\rm(Given)\\\angle Q&=\angle B\qquad\rm(Given)\\\angle P &=\angle C\qquad\rm(Given)\\\angle R &=\angle A\qquad\rm(Given)\\\end{align}

All angles two sides are equal except one side. Hence triangle \(PQR\) is not congruent to triangle \(ABC\)
