TRIANGLE DEF has vertices D(4,5) E(-4,3) F(0,-5). Determine
a)An equation of EB, the median from E to DF
b)an equation of FA, the altitude from f to DE
c)an equation of PQ, the right bisector of EF

This question doesnt really make sense to me so if u can help me i really appreciate it. : D

2. a median of triangle is a line drawn from a vertex ot the triangle to the midpoint of the opposite side of the triangle.

first find the slopes of sides of the triangle
then use point slope form to get the equations

the midpoint is just distance between vertexes divided by 2
use the distance formula

can you get it from here....

3. yea but i learned that already But i never learn how to do B and C

4. an altitude of a triangle is a line drawn from a vertex to the triangle perpendicular to the opposite side of the triangle.

c) is just a perpendicular line going thru the midpoint of EF.... at least assuming that what they mean by "right bisector" ussually its called "perpendicular bisector"

will show the math if you want... let me go home first
i am at work.... unless others help...

5. i would appreciate if you show me the calculation
thanks you
