The answers are A and D, because the definition of congruent shapes is that they are the exact same size and the same angle measures. Option A shows two right triangles, that are matching in size because of the lines on the lines showing the same size. Option d is correct because The three sides of triangle TUV match up with triangle WXY. Option C is incorrect because Angle B does not match angle G. Option b is incorrect because the triangles are not the same size.
I hope this helps!
