In a triangle A B C, take the tangent to the circumcircle of A B C at A. Reflect this line through the angle bisector at A. prove that this reflected line is parallel to B C.
I'm looking for a quick and simple proof of this fact.

The tangent is anti paralel to B C since its angles are oposite to the triangle A B C, because the semi inscribed angles. A reflexion to the angle bisector inverses the angles,so that the angles corresponds to the triangle's direction.

The ratios of the lengths of the sides B C and A C of a triangle A B C to the radius of the circumscribed circle are equal to 2 and 3 2 respectively.Find the ratio of the lengths of the bisectors of internal angles of B and C.
We are given B C R = a R = 2 and A C R = b R = 3 2 ,where R is the circumradius of the triangle A B C.
a = 2 R , b = 3 2 R
I know that m b =length of angle bisector of angle B = 2 a c s ( s b ) a + c and m c =length of angle bisector of angle C = 2 a b s ( s c ) a + b but i need the third side in order to use these formulae,which i do not know.What should i do?

In the triangle ABC, one has A = 70 o .
The point D is chosen on the segment A C such that the angle bisector A E intersects the segment B D at the point H, with the following ratios
A H H E = 3 1 , B H H D = 5 3 .
Find the angle C.

I have seen in an old geometry textbook that the formula for the length of the angle bisector at A in A B C is
m a = b c [ 1 ( a b + c ) 2 ] ,
and I have seen in a much older geometry textbook that the formula for the length of the same angle bisector is
m a = 2 b + c b c s ( s a ) .
(s denotes the semiperimeter of the triangle.)

I did not see such formulas in Euclid's Elements. Was either formula discoveblack by the ancient Greeks? May someone furnish a demonstration of either of them without using Stewart's Theorem and without using the Inscribed Angle Theorem?

I'm taking a course at teaching and we have some geometry questions. Among the questions there was one I couldn't solve.

I'm trying to prove that angle bisectors in a triangle intersect at a single point, but I need to show it analytically, i.e using line equations and distance between points. I'm familiar with proofs using geometry and vectors, but couldn't manage to show analytically. I can't use the formula of angle between lines or distance of point from a given line.

Things I've tried:

1. angle bisector theorem.
2. Writing equations of sides as A x + B y + C = 0 and then creating the equation of angle bisector - quite messy and I believe there is a lot easier way.

Thanks!

Compute the coordinate equation of the angle bisectors of the planes E and F.
E : x + 4 y + 8 z + 50 = 0 and F : 3 x + 4 y + 12 z + 82 = 0
Proceed as follows:
a) Find the normal vectors of the two angle-bisecting planes.
b) Find a shablack point of planes E and F.
c) Now determine the equations of the two angle-bisecting planes.
I have the solutions but I don't understand why I must do things the way the solution is shown.
| ( 3 4 12 ) | = 13
are the normal vectors from the equations. But this is not a good enough answer, all they asked for is the normal vectors, aren't these the normal vectors? Why must I add and subtract them like this?:
13 ( 1 4 8 ) + 9 ( 3 4 12 )
13 ( 1 4 8 ) 9 ( 3 4 12 )
b) The solution says that I must choose one component, e.g: x = 2 and then I substitute it into the equations and complete the simultaneous equation to find the point. Must it be only the x component? And why the value 2? Can it be any value? So according to the solution, the shablack point is P ( 2 , 5 , 9 )
c) The solution uses the answers from part a and b and gets this
( 10 22 53 ) [ ( x y z ) ( 2 5 9 ) ]
( 7 8 2 ) [ ( x y z ) ( 2 5 9 ) ]
Is it a general rule to use the normal to find the equation from a shablack point?
