Hey there! :)

Answer:

We can use the Pythagorean theorem to show that both triangles contain equivalent shorter legs:

Triangle A:

13² = 12² + b²

169 = 144 + b²

25 = b²

b, or the other leg, = 5 cm.

--------------------------------------

Triangle B:

c² = 12² + 5²

c² = 144 + 25

c² = 169

c = 13 cm.

---------------

Both triangles contain legs with side-lengths 5, 12, and 13 cm. The triangles are congruent because the lengths of the corresponding sides between triangle A and B are equivalent, which was proved using the Pythagorean Theorem.
