Question

Which statement is true about a right triangle?
A. The two angles other than the right angle must be total 90 degrees
B. Exactly two angles must be right angles
C. One angle must measure exactly 60 degrees
D. All three sides of a right triangle must be equal to each other

Answer 1

Its A because all angles must equal 180 degrees

Answer 2

The answer is A because if it is a 45-45-90 right triangle then all angles other than the right angle (one with the box) must be 45 and 45. 45 +45= 90. 90+90= 180.
