Answers: length of AB is about 6.7
length of CD is about 6.3
segment AB is longer
Explanation:
Each segment has two endpoints, and they are given. Then, we are asked to calculate the length of each segment, to the nearest tenth.
For this, we use the Distance Formula.
We find the distance between point A and point B, and that is the length of segment AB. Then, we round that distance to an accuracy of one-tenth.
We find the distance between point C and point D, and that is the length of segment CD. Then, we round that distance to an accuracy of one-tenth.
I have worked this out for you on the attached picture.
Hope this helps!
