I'm doing the review questions assigned for my grade 10 math exam on monday (tommorow) and i got a question about a question in the text book.

16. triangle DEF has vertices D(-2, 4), E (0, -2) and F (6, 2). Determine...

a) an equation for DG, the median from D to EF

b) an equation for FC, the altitude from F to DE

c) an equation for AB, the right bisector of DF

first off what is an altitude, median and right bisector??

The text-book answers are:

a) 4x + 5y = 12

b) x - 3y = 0

c) 4x - y = 5

The solutions (showing the steps) to those questions would be greatly appreciated

Edit: got a and b... need c still
