Which triangle is similar to triangle pqr? triangle rqs triangle qts triangle stq  triangle spr

rqs

step-by-step explanation:

we are given the triangle pqr with angle pqr = 90 degree and angle prq = 45 degree.

since, the sum of angle pqr and rqs is 180 degree, so the angle rqs comes out to be 90 degree.

as, we have the property 'aa = angle, angle' in which two triangles are similar if two angles of the both the triangles are equal.

so, we can see that as triangle pqr and triangle rqs have angles prq and qrs to be 45 degree.

hence, by 'aa' property, triangle rqs is similar to pqr.
