Question

Haley constructed the acute isosceles triangle LMN as shown in the figure below.

A horizontal line segment and a perpendicular line that meets the line segment at point L is drawn. A semi-circle with its center at L and which meets the line segment at two points is drawn. Point M lies on the arc to the right of the perpendicular line. Point N lies beyond the arc to the right of the perpendicular line

What is the error in Haley’s construction?

She did not ensure that the length of LM is different from the length of LN.

She did not plot more than one point on the arc.

She plotted
