Answer 4

What??

Answer 5

Are you familiar with the Distance Formula @desmarie ?

Answer 6

d = square root of (x1 - x2)squared + (y1 - y2) squared?

Answer 7

Yeah Exactly!
In this question too,you have to apply the distance formula and find the distance.Where is it that you are stuck? @desmarie ?

Answer 8

where do I apply what?

Answer 9

Okay..this is what I mean
You have to find the length of the sides that means the distance between the three points.
First,take the two points A and B,find the distance between them.This will be the length of one side of the triangle

Answer 10

Similarly you would take up the points B and C ,apply the distance formula and find the distance between them.This will the length of the second side of the triangle
Lastly,you take A and C points into consideration,apply the distance formula and find the length of the third side(which will be the difference)
And now you can compare the three sides and determine if your triangle is isosceles,scalene or equilateral.
I hope this is helpful:)
