Angles can be classified by size:

- Acute angle: between 0Â° and 90Â°
- Right angle: equal to 90Â°
- Obtuse angle: between 90Â° and 180Â°
- Straight angle (line): equal to 180Â°
- Reflex angle: between 180Â° and 360Â°

In a shape, an angle can be an interior angle or an exterior angle.

Angles that sum to 90Â° are called complementary angles.

Angles that sum to 180Â° are called supplementary angles.

The 5 ways to prove that two triangles are congruent are to find equal: 1) side-side-side 2) side-angle-side 3) angle-side-angle 4) angle-angle-angle 5) hypotenuse-leg

There are three ways to name an angle, provided there are only three points on the angle. Say the vertex is point A, and there are two rays extending. Each has another point on it, points B and C. You can name this angle BAC, CAB, or A.

by vertex or point

by how long it is

If you mean ways of naming angles then they are: acute, right, obtuse and reflex

Acute, obtuse, and right

Degrees, radians, or polar coordinates. (3 ways)

* acute * obtuse * right * complimentary * congruent

Right angle, equilateral, isosceles and there are also scalene and obtuse triangles.

A angle that is larger than 90 degrees

Acute and obtuse - degrees, radians?

I don't think there are rays of naming. Angles are made up of 2 rays.

Yes. There is absolutely no point in naming an invisible angle!
