Question

If triangle ABC with vertices A(-2, -5), B(-3, 2), and C (1, -2) a right triangle?

Answer 1

hello :
A(-2, -5), B(-3, 2), and C (1, -2)
calculate : AB² , AC² ,BC²
AB² = ( -3 +2 )² + ( 2 +5 )² =50
AC² = ( 1 +2 )² + ( -2 +5 )² =18
BC² = ( 1 +3 )² + ( -2 - 2 )² = 32
by petagor rule : AB² = AC² + BC²....(ABC is a right triangle in : C )
