Answer:
The triangles are congruent by either Angle Side Angle (ASA) or Angle Angle Side (AAS).
Further Explanation:
The congruent triangles are those in which all the corresponding angles and the sides are equal.
There are many congruency rules and are as follows.
1. Angle Angle Side (AAS)
2. Angle Side Angle (ASA)
3. Side Side Side (SSS)
4. Side Angle Side (SAS)
Explanation:
The sum of all the angle of a triangle is {180^ \circ }180

.
In triangle ABC the sum of all angle is {180^ \circ }180
∘
.
\begin{lgathered}\begin{aligned}\angle A+\angle B+\angle C&={180^\circ}\\{42^\circ}+{53^\circ }+\angle C&={180^\circ }\\\angle C&={180^\circ }-{95^\circ }\\\angle C&={85^\circ }\\\end{aligned}\end{lgathered}
∠A+∠B+∠C

In triangle RMQ the sum of all angle is {180^ \circ }180
∘
.
\begin{lgathered}\begin{aligned}\angle R+\angle M+\angle Q&=180^{\circ}\\42^{\circ}+\angle M+85^{\circ}&=180^{\circ}\\\angle M&=180^{\circ}-127^{\circ}\\\angle M&=53^{\circ}\end{aligned}\end{lgathered}
∠R+∠M+∠Q

∠M
∠M
=180

Consider the triangle ABC and triangle RMQ.
\angle A=\angle R={42^\circ }∠A=∠R=42
∘
Side AB = RM
\angle B=\angle M∠B=∠M
Therefore, the triangle ABC is congruent to triangle RMQ.
The triangles are congruent by either Angle Side Angle (ASA) or Angle Angle Side (AAS).
