Answer: With the compass point on G, open the compass until the pencil point is on H and draw a circle.
Explanation:
Given: Lisa is constructing an equilateral triangle. She used a straightedge to draw a segment and labeled the endpoints of the segment G and H.
We know that the equilateral triangle has all the interior angles and sides are equal.
Thus, to construct equilateral triangle from the end point G she need to take measure of the the line segment GH and then make a circle.
Similarly from point H she need to make a circle with the same measurement.
At last join the intersection point of the two circles with G and H.
Hence, the equilateral triangle is formed.
