The points (- 4, 0), (4, 0) and (0, 3) are the vertices of a


Let’s take;

A (- 4, 0),


B (4, 0),


C (0, 3) are the given vertices.


Now,


To calculate the distance between two given points;


Us the formula;


d2 = (x2 - x1)2 + (y2 - y1)2


d =


So, the distance between point A and point B;


AB =


AB =


AB = 8


Distance between B (4, 0) and C (0, 3);


BC =


BC =


BC = 5


Distance between A (- 4, 0) and C (0, 3);


AC =


AC =


AC = 5


So, BC = AC


Hence, we can say that ΔABC is an isosceles triangle because an isosceles triangle has two sides equal.
