Question

A segment with endpoints (5,8) and (-6,8) is rotated around the origin. how long will the new segment be ?

Answer 1

The rotation doesn't change the length of te segment. Let's calculate its length of AB, by applying the formula:

AB=√[(x2-x1)² +(y2-y2)²]

A(5,8) & B(-6,8) ===> √[(-6-5)²+(8-8)²] =11 units
