6-63.

Using

The perpendicular bisector of

. Added to triangle, P Q R, point D, on side, P R, with dashed line passing through D, perpendicular to side, P R.

1. Find the slope of the

line.

2. Find the midpoint

3. Substitute into the point-slope form.The median line that goes from

to the midpoint of. Dashed line Added passing through, Q & D.

1. Given the points

and, find the slope

2. Use the point-slope form of a line to find an equation.The altitude of

from to side. Dashed line added from Q, perpendicular to side, P R.

1. Find the slope of the

line.

2. Then using the slope and pt., use the formto find.

3. Then substitute backand back into the form.
