Question

On a number line, the coordinates of j, k, l, m, n are −10.5, −4, −1, 1.5, 4 respectively. find the lengths of the two segments. are they congruent? jk¯¯¯¯¯¯ and km¯¯¯¯¯¯¯

Answer 1

Answer:

• JK = 6.5
• KM = 5.5
• not congruent

Step-by-step explanation:

JK = K-J = (-4) -(-10.5) = 6.5

KM = M -K = 1.5 -(-4) = 5.5

6.5 ≠ 5.5, so the segments are not congruent.
