Geometry Final Review #1

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

• d = √((x2 - x1)² + (y2 - y1)²)

• d = (x1 + x2) / 2

• d = (y1 + y2) / 2

• d = (x2 - x1) + (y2 - y1)

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

• M = (x1 + x2, y1 + y2)

• M = (x1 - x2, y1 - y2)

• M = ((x1 + x2) / 2, (y1 + y2) / 2)

• M = ((x1 - x2) / 2, (y1 - y2) / 2)
