To bisect an angle is to divide the angle in half.
One half of a right angle is a 45 degree angle.
Double angle and half angle in mathematics refer to the formulas used to express trigonometric functions of angles equal to 2a or 1/2a. These are known as the double-angle and half-angle formulas.

A quarter section is a unit of land measurement that is 160 acres in size. It is equal to half of a half section of land.
To bisect an angle is to divide the angle in half.
Measure each of the sides that form the right-angle, half one of the measurements and multiply by the other (full) measurement. That gives you the area of the triangle. In simple terms - half the base times the height.
A half angle is just what it sound like; it's half the measure of an angle. If you have an angle of 30 degrees, the half angle is 15 degrees. Simple and easy. Where it comes in handy is in construction of something like, say, an isosceles triangle inside a circle. If you have the two equal equal angles, you can find the third angle. Then you can construct it by drawing a chord across the circle through its diameter, then using the half angle to draw in one side. Repeating the process on the other side of the diameter will give you the other side of the triangle. By drawing in a chord connecting the points where the other two chords (drawn off the half angles on either side of the diameter) intersect the circle, you'll have completed the construction of the isosceles triangle.
One half of a right angle is a 45 degree angle.
Double angle and half angle in mathematics refer to the formulas used to express trigonometric functions of angles equal to 2a or 1/2a. These are known as the double-angle and half-angle formulas.
15 degrees is not a special angle, but it is half of 30, which is a special angle. If you need sin 15 you can use the half angle formula with 30 degrees.
to bisect an angle means to cut it in half
Complimentary angles are two angles that add up to 90o. It the sum of two angles is 90o, and one is twice as big as the other, then we can make up a little equation to solve for that larger angle (a). It might look like this: 90o = a + ( a / 2 ) As our larger angle (a) was said to be twice as large as our smaller angle, our smaller angle (a/2) is half as large as the larger angle. 90o = 3a / 2 180o = 3a a = 180o / 3 = 60o Our mystery angle is a 60o angle. The smaller one is 30o. The larger angle is twice the smaller, and they two sum to 90o. Our work checks.
