2. Medians and Altitudes of Triangles

Exercise 29 Page 423

JM and KM are congruent segments, so M is a midpoint of JK.

Median.

Practice makes perfect

We are given that JM is congruent to KM. This means that their measures are the same. Thus, M is a midpoint of JK.

Now, let's recall that a median of a triangle is a segment with endpoints being a vertex of a triangle and the midpoint of the opposite side. As we can see, the endpoints of LM are L, the vertex of △ JLK is L, and M the midpoint of the opposite to the L side JK. We conclude that LM is a median of △ JLK.
