Construct an equilateral triangle of perimeter 19.5 centimeter.Measure and verify that each angle measures 60 digrees

Answer 1

Where the circles intersect above (or below) the line will be the third vertex of the triangle, since all three sides are the same.

Get out your protractor and measure the angles.
