Question

Andy says if a triangle has two 45 degree angles then the third triangle has to be less than 90 degrees. Miguel does not agree with Andy. Why might Miguel not agree with Andy? Who is correct, and why?

Answer 1

Miguel, because Andy is incorrect.

Explanation:

The Angle Sum Theorem tells you the sum of angles in a triangle is 180°. If two of the angles are 45°, the third must be 180° -45° -45° = 90°. The third angle cannot be less than 90°.

Miguel is correct to disagree with Andy.
