I'd really need to see a sketch of the problem. Your description leaves
too many fuzzy details.
triangles angle bisector is called incenter..
cosine
Yes because tangent = opposite/adjacent
This ratio is the tangent of the angle.If the triangle is a right angled triangle and the angle in question is not the right angle, then it is the tangent of the angle in question.
The perpendicular bisector bisects the angle at the vertex.
Yes. The bisector of one angle of a triangle is the perpendicular bisector of theopposite side if the bisected angle is the vertex angle of an isosceles triangle,or any angle of an equilateral triangle.
Only if the vertex angle being bisected is between the sides of equal length will the result be two congruent triangles.
The secant of an angle in a right triangle is the hypotenuse divided by the adjacent side. The tangent angle of a right triangle is the length of the opposite side divided by the length of the adjacent side.

A perpendicular bisector is a straight line that divides a side of a triangle in two and is at right angles to that side. An angle bisector is a straight line that divides an angle of a triangle in two.
Angle bisector

It is a tangent.
angle bisector
The perpendicular bisector bisects the angle at the vertex.
