- Author:
- Tim Brzezinski

- Topic:
- Algebra, Coordinates, Geometry, Straight Lines

## Directions:

In the app below, reposition the four points so that

- The dashed line is perpendicular to the segment
- The dashed line bisects the segment
- No coordinate repeats

**check**button to see how well your setup satisfies the first two criteria. An "x" means at least one coordinate repeats. A check mark indicates no coordinates repeat.## Algebraically show how your setup above satisfies the first two criteria.

## Create another setup so that the slope of the segment and line are entirely different from the slopes of the segment and line from your setup above.

## Algebraically show how your setup above satisfies the first two criteria.
