The description requires you to say how much of a whole circle is represented by the angle. There are several measurement units, but the most common two are degrees (for introductory geometry) and radians (advanced geometry). A whole turn comprises 360 degrees or 2*pi radians.
The opposite angles are congruent and all add to 360 degrees
Inside a rectangle with its diagonals drawn in, there are 36 different angles. Describe which one you're interested in, and we'll describe how to measure it.
Yes, congruent angles are angles that have the same measure.
solutions of the equation: x2-x=20
Angles with the same angle measure are congruent.

use a protractor to measure angles
Degrees are used to measure angles.
Angles with the same angle measure are congruent.
Eratosthenes measured the size of Earth by using the Sun's angles, as well as a bit of geometry.
A rhombus or a parallelogram
Individual angles can have near enough any measure.
complementary angles
Congruent angles (or equivalent angles) have the same angle measure.
