Question

Sayed is constructing a triangle DEF congruent to triangle ABC. First, he drew a line segment congruent to BC and labeled it EF. Next, he adjusted the width of the compass to half of the length of side AB and drew an arc above segment EF from point E.

Which statement about the arc he drew is true?

Answer 1

It is incorrect because the width of the compass was not adjusted to the corresponding side AB.

It is correct because side DE is the corresponding side for segment AB.

It is correct because the use of compass preserves the congruency of corresponding angles.

It is incorrect because a ruler should have been used to draw a segment congruent to segment AB.

Answer 2

It is incorrect because the width of the compass was not adjusted to the corresponding side AB.
