b. they form a right angle.
c. they are equal.
d. they are congruent.

The Answer to this question is D- They are Congruent

Option D and Option C are correct.

Step-by-step explanation:

Given if two line segments have the same length then we have to choose the correct option.

Option A. They share an endpoint.

Two line segments with same length not results the end points are same as shown in attachment. They does not share an end point still are of same length.

Option B. They form a right angle.

Two line segments with same length not results the end points are same as shown in attachment i.e not necessary these two are joined or formed an angle.

Option C. They are equal

Line segments are congruent if they have the same length.

Congruent means equal.

Option D. They are congruent.

Line segments are congruent if they have the same length.
