What is the number of bisectors that can be drawn of a given angle?

Let's assume you want to bisect a 60° angle using a compass and straightedge. Place the point of the compass at the 60° angle's vertex. Strike an arc through the...

Check the angles between either of the original rays and the bisector line. If they are equal, then the line is the exact bisector.

This is more a matter of intuition than proof. It's the subject of Euclid's Parallel Postulate. It's considered an axiom and has been the subject of much controversy for centuries.

Yes, your suggestion will work. You also may find Method 3 to be less confusing than the other methods shown. Method 3 is just a variation of the method you're...

When you make the first arc, at points x and y in this article, you are actually marking the lengths of two sides of a triangle. When you draw the...

If you're not given the central angle, you'll typically be given the sector area of the arc. To find the arc length with a sector area, multiply the sector area...

That is correct. The vertex of an inscribed angle is on the outside of a circle. When an inscribed angle and a central angle share the same arc on a...

If given force is F and it is at an angle x with the x-axis. Take its x component as F cosx. Its y component is F sinx.

Take the 90, add it to 35. This gives you 125 degrees. Triangles can only ever add up to 180, thus take the difference of 125 and 180 (180-125). This...

A right angle triangle always consists of one 90 degree angle, and every triangle must equal 180 degrees. Here is the work for this problem: 90 degrees (representing the right...
