Question

Martha is constructing a triangle KLM congruent to triangle PQR shown.



She marked a point K, adjusted the width of the compass to the length of PR and drew an arc from point K. She marked a point M on the arc. Next she adjusted the width of the compass to the length of PQ and drew an arc from point R. What error did Martha make in this step?

Not making the arc from point K.

Making an arc instead of a circle.

Not using a ruler to measure PQ.

Changing the width of the compass.
