Geometry and Trigonometry practice question
In a right triangle, the two legs have equal length. What is the measure of each acute angle?
- A. 45°Correct
- B. 30°
- C. 60°
- D. 90°
Answer: A. 45°
Equal legs give tan = 1, so each acute angle is 45°.
Why the other answers are wrong
- B. 30°
- 30° would need the opposite leg to be half the hypotenuse.
- C. 60°
- 60° would need unequal legs.
- D. 90°
- 90° is the right angle itself.
