Sid is constructing a triangle PQR congruent to triangle LMN. First, he constructed a segment PQ congruent to segment LM. Next, he measured the segment LN with a ruler and used the measurement to draw the segment PR.

Which statement about segment PR is true?

Which statement about segment PR is true?

anonymous · Answer

A       It is correct because it is congruent to line segment LN.
	B	It is incorrect because it is not congruent to line segment NM.
	C	It is correct because use of ruler gives an accurate measurement.
	D	It is incorrect because a ruler is not used to construct congruent triangles.

D
it's incorrect because he must also measure MN to get a congruent triangle
or measure the angle (LM,LN)
