It depends on what you mean by bisect. All rectangles have diagonals that bisect the other one. Only certain rectangles (Squares) have diagonals that bisect its vertex, the ninety degree angle.
Complementary angles sum to give 90 degrees. Therefore the complement to an 85 degree angle is a 5 degree angle.
You find the center of a screwed 45 degree elbow by bisecting the angle.
With a protractor and a straight edge.
bisect
Use a protractor or bisect a 45 degree angle with a compass and a straight edge
If you bisect a 30 degree angle, you end up with two 15 degree angles.
Well, darling, an 85 degree angle is called an "acute angle." It's like a cute little angle that's smaller than a right angle but bigger than a straight angle. So, next time you come across an 85 degree angle, just remember it's acute and adorable.
Draw a line segment AB. Put your compass point at B and stretch the compass out until it is at point A. Now draw a circle. Now move the compass point to B, leaving the compass opening the same as before and draw another circle. The circles will intersect in two points. Call them C and D. Draw CD and name its intersection with AB as the point E. angle CEB is a right angle. Now you need to bisect the 90 degree angle you just constructed to get two 45 degree angles. Look in your book as to how to bisect an angle. The angle CAB = 60 degrees. So bisect it to get a 30 degree angle and then bisect it to get a 15 degree angle. You can get a 105 degree angle by adding the 90 degree angle and the 15 degree angle. Similarly, you can get a 75 degree angle by subtracting the 15 degree angle from 90 degrees. Look in your book on how to copy an angle.

85 degree
Complementary angles sum to give 90 degrees. Therefore the complement to an 85 degree angle is a 5 degree angle.
Draw a right angle (90o). Bisect the right angle and there will be two 45o angles. Bisect one of the 45o angles and there will be one 45o angle and two 22.5o angles. A 67.5o angle includes the 45o angle and the 22.5o angle next to it, totaling 67.5o.
Easy if you know how to draw a perpendicular and to bisect angles. Draw a perpendicular = 90 degrees. Bisect it = 45 degrees Bisect that = 22.5 degrees. Not sure how you can do it without that knowledge.
bisect between 120 and 180 degree ( 120 + 180= 300/2 =150)
You find the center of a screwed 45 degree elbow by bisecting the angle.
A 90 degree angle can be bisected into two 45 degree angles with a compass and straight edge The diagonals of a square bisect their opposite corners into 45 degree angles
