Chapter 4: Q11. (page 144)

Tell which pairs of congruent parts and what methods $(S S S, S A S, A S A, A A S, or H L)$ you would use to prove the triangles are congruent.
Given: $鈭� 1 鈮� 鈭� 2; 鈭� 3 鈮� 鈭� 4; \overset{炉}{QR} 鈮� \overset{炉}{TS}$
$鈻� QPR 鈮� 鈻� TPS$ by what method?

Short Answer

Expert verified

The congruent parts in the triangles $鈻� Q P R$ and $鈻� T P S$ are:

$PQ 鈮� PT, QR 鈮� TS$ and $PR 鈮� PS$ .

The triangles $鈻� Q P R$ and $鈻� T P S$ are congruent by $S S S$ postulate.

Step by step solution

- Observe the given diagram.

The given diagram is:

- Write the theorem 4-2.

The theorem $4 - 2$ states that if two angles of a triangle are congruent, then the sides opposite to those angles are congruent.

- Description of step.

As, $鈭� 1 鈮� 鈭� 2$ , therefore by using the theorem $4 - 2$ , it can be said that sides $P R$ and $P S$ are congruent sides.

Therefore, $P R 鈮� P S$ .

As, $鈭� 3 鈮� 鈭� 4$ , therefore by using the theorem $4 - 2$ , it can be said that sides $P Q$ and $P T$ are congruent sides.

Therefore, $P Q 鈮� P T$ .

It is also given that $Q R 鈮� T S$ .

In the triangles $鈻� Q P R$ and $鈻� T P S$ , it can be noticed that $P R 鈮� P S, Q R 鈮� T S$ and $P Q 鈮� P T$ .

Therefore, the triangles $鈻� Q P R$ and $鈻� T P S$ are the congruent triangles by using the $S S S$ postulate.

- Write the conclusion.

The postulate that proves the triangles $鈻� Q P R$ and $鈻� T P S$ are congruent is $S S S$ postulate.
