Question

What data must be given to construct an equilateral triangle using a compass and a ruler?

• A. One side
• B. One angle
• C. Two sides
• D. One angle and one side

Answer 1

The correct option is A One side

We know that in equilateral triangle, all three sides are equal, and all three angles are congruent and are equal to 60 degrees.
Thus, to construct an equilateral triangle, no data needs to be given about its angles, but one side length is required.
