(8.G.8)Edit
The questions below assess the prerequisite standards needed for this Lesson.
-
Look at Part 1. How can you use the ordered pairs to find the length of
\overline {AD} ? Why?Subtract the
y -values of pointA and pointD , becausey -coordinates tell you vertical length. -
-
How can you use the ordered pairs to find the length of
\overline{CD} ? Why?Subtract the
x -values of pointC and pointD , becausex -coordinates tell you horizontal length. -
-
In Part 2, how can you find the length of the hypotenuse, given the lengths of these legs?
Plug the leg lengths into the Pythagorean Theorem.

Plug in 7 and 24 into
a^{2}+b^{2}=c^{2} . Do not evaluate. What does the equation look like?7^{2}+24^{2}=c^{2} -
