Question

$\Delta ABC$ is congruent to $\Delta RQP$, that is $\Delta ABC\cong \Delta RQP$. If $\angle C$ and $\angle P$ are the smallest angles in $\Delta ABC$ and $\Delta RQP$, then which of the following is not true?

• A. ∠A
• B. ∠C
• C. ∠B
• D. Both ∠A and ∠B

Answer 1

Answer: (A), (B)

The correct options are
A

∠A

B

∠C

If two triangles are congruent, then their corresponding angles are equal.
Therefore the smallest angles in the two triangles will be equal.
Since, $\Delta$ ABC $\cong$ $\Delta$ RQP

Therefore, $\angle R$ =$\angle A$

$\angle Q$ =$\angle B$

$\angle P$ =$\angle C$
