Question

5 multiple choice 1 point which of the following diagrams illustrates segment ad as a median? 6 multiple choice 1 point

Explanation:

Step1: Recall median definition

A median of a triangle is a line - segment that joins a vertex of a triangle to the mid - point of the opposite side.

Step2: Analyze each option

In the first option, the right - angle symbol indicates an altitude. In the second option, the angle - bisector symbol indicates an angle bisector. In the third option, the equal - length marks on BD and DC show that D is the mid - point of BC. So, AD is a median. In the fourth option, the equal - angle symbols indicate an angle bisector.

Answer:

The third diagram (the one where there are equal - length marks on BD and DC) illustrates segment AD as a median.
