The coordinates of the vertices of ∆pqr are p(-2,5), q(-1,1), and r(7,3). determine whether ∆pqr is a right triangle. show your work and explain your answer!

Step 1

Plot the vertices of triangle PQR

using a graphing tool

see the attached figure

we know that the distance between two points is equal to

Step 2

Find the distance PR

substitute the values

Step 3

Find the distance QP

substitute the values

Step 4

Find the distance QR

substitute the values

Step 5

If triang;le PQR is a right triangle

then

Applying the Pythagorean Theorem

substitute the values

---------> is true

therefore

The answer is

The triangle PQR is a right triangle

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
