Show that the points form the vertices of the polygon.

Question

right triangle:    (−4, −1), (0, 1), (2, −3)

distance between (-4,-1), (0,1) d1=________units?

distance between (0,1), (2,-3) d2=________units?

distance between (-4,-1) (2,-3) d3=_______units?

Answer 1

Using the Distance Formula d= sqrt[(x₂-x₁)² + (y₂-y₁)²]

d₁= sqrt[(0+4)² + (1+1)²] ≈ 4.47

d₂= sqrt[(2-0)² + (-3-1)²] ≈ 4.47

d₃= sqrt[(2+4)² + (-3+1)²] ≈ 6.32
