Question
△DEF and are shown below. Are these triangles similar?
Similar
Not similar
Angles similar
Angles similar
The correct answer is: Not similar
m ∠D + m ∠E + m ∠F = 180° m ∠D + 90° + 32° = 180° m ∠D + 122° = 180° m ∠D = 58° The angles in △DEF are 58°, 90°, and 32°. But since △JKL has a 52° angle and △DEF does not, △DEF is not similar to △JKL.
