Question

find the nature of the triangle with vertices (-4,0),(4,0) and (0,3)

Answer 1

this question you use formula distance formula root x square - X 1 equals to root y square minus y1

Answer 2

use distance formula, (in coordinate geometry)
P(-4,0) Q(4,0) R(0,3)
find distance between PQ, then QR, then PR.
then you'll be able to determine whether the triangle is isosceles or scalene or equailateral
