Answer:
See below
Step-by-step explanation:
<u>Given points:</u>
- A (3, -1)
, B (9, 2)
, C (6, -4)
First, plot the points on the coordinate plane (see attached)
<u>We see that AB and BC look the same. Let's find their length:</u>
- AB =
- BC =
We showed that AB = BC = 3√5, so the triangle has two sided of the same length, therefore is isosceles.
Step-by-step explanation:
just guess and see
