Step-by-step explanation:

You need to find one of the following proves:

  1. SSS   (side, side, side)
  2. SAS   (side, angle, side)
  3. ASA   (angle, side, angle)

1) The firs one is mentioned - ∡MRQ = ∡NQR

2) QR is common for both triangles

3) PQ = PR -> that means triangle is equilateral and angles ∡PQR = ∡QRP

Now you now 2 angles and 1 side are the same.

Using ASA (angle, side, angle) that's prove both triangles are congruent.
