DRAWING NOT TO SCALE 2. In Figure 2, ABC is a right triangle and BD is...
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.
c) Consider the figure below. It is given that A ABC is a 30-60° right triangle, A DEF is an isosceles triangle with DF = EF, DE | AC, ZDEF = 65°, ZDIL = 38.2, and ZIK) = 31'. Find all angles in the figure and mark them on the figure. Clearly show all your work B D G E A
△ABC is a right triangle with
right angle C. Side AC is 6 units longer than side BC . If the
hypotenuse has length 52–√ units, find the length of AC.

Do not use I=delta/S!!! Use law of cosines
Here is the question: Let r be the radius of the incircle of triangle ABC on the unit sphere S. If all the angles in triangle ABC are right angles, what is the exact value of cos r? Note in spherical geometry the angles sum is>180 Using below picture (this is what we are given), we should know angle b and the angle at the perpendicular. If we find the length on...
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.
