Geometry and Trigonometry practice question
A right triangle has two sides of equal length. What is the measure, in degrees, of each of its two acute angles?
Answer: 45
Equal legs mean equal acute angles, and they sum to 90: each is 45.
Common wrong answers
- If you answered 30
- 30 would leave the other acute angle at 60, so the legs would not be equal.
- If you answered 60
- 60 belongs to an equilateral triangle.
- If you answered 90
- 90 is the right angle.
