Which pair of triangles is congruent?

A congruent shape is a shape that has the exact same shape and size as another. therefore, I believe that the first, second, and third pairs are congruent. If it could only be one pair, I think the last one.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
