Distance formulas

Front

What is the distance formula for two points (x₁, y₁) and (x₂, y₂)?

Back

Distance = √((x₂ - x₁)² + (y₂ - y₁)²)

Front

If point M is the midpoint of line segment AB, and A has coordinates (x₁, y₁), how do you find the coordinates of point B?

Back

B = (2x₁ - xₘ, 2y₁ - yₘ) where M = (xₘ, yₘ)

Back

Distance = 5

Front

What is the midpoint formula for two points (x₁, y₁) and (x₂, y₂)?

Back

Midpoint = ((x₁ + x₂)/2, (y₁ + y₂)/2)
