Which triangle is similar to ABC and why?

ΔJEL

Step-by-step explanation:

When 2 triangles are similar, they have at least 2 congruent angles (this is the AA Similarity Postulate). None of our choices have both 65° and 50°, so let's find ∠C. We know that 65° + 50° + ∠C = 180° (because the sum of all angle measures in a triangle is 180°), and when we solve we get ∠C = 65°. Now, we have to look for a triangle that has at least 2 of these angle measures. ΔJEL has 2 65° angles, and so does ΔABC, so this means that ΔJEL and ΔABC are similar. Hope this helps!
