Which triangle is not similar to the other two triangles?
1 answer:
Answer:
First choice top-down
Step-by-step explanation:
The Similarity Theorem Side-Angle-Side it can be checked here to see what triangles are similar.
All 3 triangles have 2 congruent sides so the triangles are all isosceles.
The base angles of isosceles triangles are congruent so knowing this and that the sum of angles in a triangle is 180° we can calculate the measure of all angles.
180-20 = 160; 160/2 = 80°
180-30 = 150; 150/2 = 75°
Now we can conclude that Δ JLK is not similar with Δ MNO ≈ ΔPRQ
