Period 4
1. Q: Let triangle ABC be a right triangle with AB = 17, BC = 15, and CA = 8. Let CD be the altitude to the hypotenuse and let the median from B to AC intersect AC at F and CD at E. Find BE/EF and CE/ED.
A: BE/EF = 450y/64y = 225/32, CE/ED = 289z/225z = 289/225
2. Q:
In the figure shown, AF = 3, AD:DC = 5:4, and CF intersects BD at G so that BG:GD = 9:1. Find BF.
A: 12
3. Q:
In the figure shown, AO = 7, AD:DB = 2:3, and BE:EC = 7:3. Find AO:OE.
A: AO/OE = 7 / (63 / 20) = 140 / 63 = 20 / 9
4. Q: Point E is selected on side AB of triangle ABC in such a way that AE:EB = 1:3 and point D is selected on side BC so that CD:DB = 1:2. The point of intersection of AD and CF is F. Find EF/FC + AF/FD.
A: EF/FC + AF/FD = d/2d + c/c = ½ + 1 = 1 ½
5. Q:
In the figure shown, AB/BC = 4/5 and CD/CE = 2/1. Find CG/GF.
A: CG/GF = 13z/4z = 13/4
