Let ABC be a right triangle with hypotenuse AC. Let BD
be the altitude to the hypotenuse. Let BE be the angle bisector of
angle DBC, and AF be the angle bisector of angle DAB. Prove EB is
perpendicular to FA.
hint for d): consider a point D such that M is the
midpoint of CD. Which segments are congruent here? Do you see a
triangle with all three side lengts given.
Could you please write some instructions on the side
so I know how to follow your solution?
5. Given a triangle ABC, let M be the midpoint of the segment AB. The segment CM is called the median of the triangle. Let T be the point on the line...

Given a triangle ABC, let l_1 be the angle bisector of <A
and let l_2 be the perpendicular bisector of line BC. Assuming AB
> AC, show that l_1 intersection l_2 is not in triangle
ABC
Excuse l_2 is the perpendicular bisector of line BC hence the right
angle. The questions is to show a step by step proof that when l_1
abd l_2 intersect, it will be outside of the given triangle.

Let traingle ABC have midpoint B' on AC, C' midpoint of AB and G be centroid. If AC=5, AB=5, and CC'=6 find BC.
1. Consider the isosceles triangle ABC, with AB = AC, and BAC = 20. Choose points E, D on the sides AB, AC, respectively, so that ZCBD = 60', and BCE = 50'. We will find LEDB. (i) Bring the parallel DF to BC, with F on AB. Connect points and F. and let K be the intersection of BD and CF. Show that DFBC is an isosceles trapezium. Mark all its angles. (ii) What type of triangles are BKC...
Points W and X are chosen on the side AB of triangle ABC and points Y and Z are chosen on side AC. Suppose that cr(A,W,X,B)=cr(A,Y,Z,C) and that WY is parallel to XZ. Prove that XZ is parallel to BC. Hint: let T be the point where the parallel to XZ through B meets line AC. Note that neither a nor Y can lie on segment TC and use excercise 3C.2 to show that T is C. cr=cross ratio
