An angle has 3 parts.
Two intersecting lines/line segments and the point
of intersection (called the vertex of the angle.)
The amount of rotation required to bring one of the
line segments to coincide with the other is called
the value the angle. The most common units of measuring angles are degrees and radians.

first angle projection and third angle projection.
A right angle might be described as a ninety-degree angle. It can also be described as perpendicular or orthogonal.
The angle of incidence is equal to the angle of reflection when a wave, such as light, strikes a reflective surface. This principle is known as the law of reflection. Both angles are measured from a line perpendicular to the surface at the point of incidence, called the normal. Thus, if the angle of incidence is 30 degrees, the angle of reflection will also be 30 degrees.
A straight line is equal to a 180 degree angle.
High angle is when the camera looks down on someone or something.
right angle
the interoir angle the exterior angle and the full angle
The parts are arm vertex and ore
It is dividing an angle into two equal parts.
An angle bisector.
An angle bisector.
It is called an arm of the angle.
Bisecting an angle
You can tell if a ray is bisecting an angle if the angle is cut directly in half into two congruent parts.
if u divide it into 2 equal parts its a half
An angle bisector is a line. A bisector is something that cuts something into two equal parts. The line passes through the angle dividing it into two equal parts and is called an angle bisector.
