Question

Each angle of an equilateral triangle is:

• A. 90°
• B. 30°
• C. 45°
• D. 60°

Hint:

In an equilateral triangle, all angles are 60° because the sum of angles in any triangle is 180°.

Answer 1

The Correct Option is D

Step 1: Understanding an Equilateral Triangle.
An equilateral triangle is a triangle where all three sides are of equal length. The angles in an equilateral triangle are also equal. The sum of the angles in any triangle is 180°. Since all angles in an equilateral triangle are the same, each angle must be \( \frac{180°}{3} = 60° \).
Step 2: Verifying the Options.
- Option (1): 90° is the angle in a right triangle, not in an equilateral triangle.
- Option (2): 30° is too small for an equilateral triangle.
- Option (3): 45° is the angle in an isosceles right triangle, not an equilateral triangle.
- Option (4): 60° is the correct answer, as each angle in an equilateral triangle is 60°.
Conclusion:
Therefore, the correct answer is (4) 60°.
