Hello everyone! can someone me, i don`t
would be really appreciated. you.

is δ abc a right-angled triangle? a(3, -3), b(2, 1) and c(7, -2). show your work and explain how you arrived at your answer

Step-by-step explanation:

You have to find the slope

Slope= y₂ - y₁ / x₂-x₁

A(3, -3), B(2, 1)  

Slope of AB  m₁ =  1-[-3] / 2-3 = 1+3 / -1 = 4/-1 = -4

  B(2, 1)  ; C(7, -2)

slope of BC m₂=  -2-1 / 7-2 = -3/5

A(3, -3) ; C(7, -2)

Slope of AC m₃ = -2-[-3] / 7-3 = -2+3 / 4 = 1/4

m₁ * m₃ = -4 * (1/4)      = -4/4 = -1

When the product of slope is (-1), then two lines are perpendicular.

So AB and AC are perpendicular.  Δ ABC is a right-angled triangle

dude thats to long figure it

hey pal. the answer is b plz mark as brainliest
