Really need on these ! on a number line, the coordinates of a, b, c, and d are -5, -2, 0, and 3 respectively. find the length of each segment. are they congruent? 1) segment a b. and segment c d. 2) segment a c. and segment b d. 3) segment b d. and segment a d. solve for each number 1, 2, & 3 they aren't answers they need solved for. (so no one misunderstands

Segment AB is 3 units long

Segment AC is 5 units long

Segment AD is 8 units long

Segment BD is 5 units long

Segment CD is 3 units long

To find the length of the segment, you are finding the distance between the two endpoints. On a number line, distance is simply found through subtraction and making the result positive. Point A is at -5 while point B is at -2. Subtract these values to get -5 - (-2) = -5+2 = -3 and make the result positive to get 3. So the distance from A to B is 3 units, which is the same as saying "segment AB is 3 units long"

Segment AC is 5 units long because A-C = 5-0 = 5

Segment AD is 8 units long since A-D = -5-3 = -8 which turns positive into 8

Segment BD is 5 units long because B-D = -2-3 = -5 which becomes 5

Segment CD is 3 units long because C - D = 0-3 = -3 which turns into 3

Note: An alternative to subtraction is to count out the spaces between each number on the number line.
