Question

Wat do I do I don't know

Answer 1

I can't see all the triangles, but basically, it is asking you to write down triangles that are congruent with each other.

The marks in the corner of the triangle indicate that the angles of that triangle are congruent to the other triangle.

So,

Triangle NOP= Triangle NQP

Make sure that the points align with each other, otherwise you could be saying that two different triangles are congruent to each other. 

N= N   O=Q  P=P  

I hope this cleared some confusion!
