Review for Finals 2: Midpoint & Distance Formula

Front

What is the definition of midpoint?

Back

The point that divides a line segment into two equal parts.

Front

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

Back

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

Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front
