# What have I done wrong in this Q? Congruent triangles GCSE

Announcements
#1

-We are given that triangle PQR is an isosceles triangle in which PQ = PR -Since the base angles of an isosceles triangle are equal, angle PQR = angle PRQ
-And we are given that angle MRQ = angle NQR
-And we know that QR = QR - shared side
-triangles QNR is congruent to triangles RMQ - ASA - congruent angle side angle

I got 2/4, what's wrong?

It looks fine to me. Is this an online working checker that’s giving you 2/4?

Yes, it was Mathswatch. But it's cool now, I finally got it to mark me correctly

I thought so. Often with Mathswatch getting it to understand that your working is correct is harder than the actual maths
