Question

name the type of triangle formed by the points A (-5,6), B (-4,-2), C (7,5)?

Answer 1

A (–5, 6), B (–4, –2) and C (7, 5)

AB = √{(-4+5)² + (-2-6)²}
= √1+64
=√65

BC=√{(7+4)² + (5+2)²}
=√121 + 49
=√170

AC=√{(7+5)² + (5-6)²}
=√144 + 1
=√145

Note: The formula used is
Distance d= √{(X2 - X1)² + (Y2- Y1)²}

All sides are different in measure, so ABC is a scalene triangle.
