For triangle A(-6,6), C(2, 10) , B (4, -4) find the equation of the median from the vertex A.
For triangle A(-6,6), C(2, 10) , B (4, -4) find the equation of the median from the vertex B.
Could a segment be both a median and an altitude?
Yes! We call this a perpendicular bisector. However, not all perpendicular bisectors go
through a vertex.
Name the segments from the given figure.
Altitude:__________ Median: __________ Perpendicular bisector _________
Angle bisector ____________

In ∆DEG FH is a perpendicular bisector of DG with H on DG . If DH = 2y +3, GH = 7y –
42, and m∠FHG = ( x 2 + 9) , then find the value of x and y. What is the measure of DG?
