Determine whether the triangle defined by the points p(-1, 3), q(2,6) r(5,3) is isosceles, scalene, or equalateral. show work and round to nearest tenth.

Hi there!

I have included a graph of the image below for your reference. 
Let's start by figuring out the distance of all three sides using the distance formula: PR = 6 units, PQ = 4.2, RQ = 4.2. Therefore, because two sides are congruent, the triangle is isosceles.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
