The points A(-4, 0), B(4, 0) and C(0, 3) are the vertices of a triangle, which is
The distance between any two points P1(x1, y1) and P2(x2, y2) is given by the following formula:
⇒
⇒ Distance AB =
=
= 8
⇒ Distance BC =
=
= 5
⇒ Distance AC =
= √(9 + 16)
= √25
= 5
Since the length of two sides is equal, given triangle is an isosceles triangle.
