Graph the trapezoid A(6, 5), B(8, −2), C(−4, −2), D(−2, 5). Homework Help ✎

Your graph should look like the one below.

1. Find the length of the bottom base (segment CB). Then find the length of the top base (segment AD). Use grid units.

• Both B and C are on the y = −2 line, so you just need to find the the distance between their x-coordinates to determine the length of CB. The same can be done for AD.

$\text{The length of segment }CB \text{ is }\left | 8 \right| + \left | -4 \right | =\ 12.\text{ Now find the length of segment } AD.$

1. Find the distance between the two bases, which is called the height. Use grid units.

• Use a similar method to part (a), but use the y-coordinates to find the distance between segment CB and segment AD.
