When you evaluate the expression   f(d - e)   for d = 4, e = 24, and f = 4 your solution is 112

True or false?

We require the congruence between another pair of corresponding angles to say that those triangles are similar by the Angle-Angle Postulate.

Step-by-step explanation:

To prove that the two triangles similar we can use these postulates:

Angle-Angle Postulate: if two pairs of corresponding angles between two triangles are congruent, then, those triangles are similar.Side-Side-Side Postulate: if all corresponding sides between two triangles are proportional, or they are in a same proportion, then, those triangles are similar.Side-Angle-Side Postulate: If two pairs of corresponding angles are proportional, and one pair of corresponding angles (which are formed by the proportional sides) are congruent, then, those triangles are similar.

So, in the problem, we know that one pair of corresponding triangles are congruent. Now, we require the congruence between another pair of corresponding angles to say that those triangles are similar by the Angle-Angle Postulate. That's the shortest way.
