I'm guessing that you don't really want the formulas.  I think what you actually want
is the definitions of those functions of an acute angle when it's in a right triangle.

Cosine = (adjacent side) / (hypotenuse)

Tangent = (opposite side) / (adjacent side)

Sine = (opposite side) / (hypotenuse)

Tell me if I'm wrong, and I'll find some formulas for you.

Answer:

1)An angle bisector is basically the division of an angle into two equal parts, so you should just draw a line in the middle after you found the angles using the compass

2) parallel lines is a pair of lines that never intersect, and are always the same distance apart. you should use the compass to draw a 90-degree angle at the end of the line XY, and use the straightedge to draw a line that is parallel to the line XY.
