Question

In triangle ABC, angle A is 75o and angle B is 20o. Select the triangle that is similar to triangle ABC.

Answer 1

Answer:

A. $\triangle$DEF where $\angle D = 75^{\circ}$ and $\angle E = 20^{\circ}$.

Step-by-step explanation:

At first we must keep in mind that two triangles are similar when they have same angle configuration, that is, each pair of angles is congruent. If $\triangle$ABC and $\triangle$DEF, then $\angle A \equiv \angle D$ and $\angle B \equiv \angle E$. Hence, $\angle D = 75^{\circ}$ and $\angle E = 20^{\circ}$.

In a nutshell, correct answer is A.
