a triangle with vertices J(2, 1), K(2, 6), and L(8, 3), and M is the midpoint of segment JK and N is the midpoint of segment KL comma what is the length of MN?

Question

Given a triangle with vertices J(2, 1), K(2, 6), and L(8, 3), and M is the midpoint of segment JK and N is the midpoint of segment KL comma what is the length of MN?

Answer 1

|MN| = |JL| / 2

 

= (1/2)√[(3 - 1)² + (8 - 2)²]

 

= (1/2)√40

 

= √10
