Types of Angles:

The sum of angles around a point = 360°
The sum of angles on a straight line = 180°

Angles in Parallel Lines:

Two lines that lie in the same plane and never intersect are defined as parallel lines. They are equal distance apart from each other and have the same slope.

A transversal, a third line intersecting two parallel lines, forms specific angle relationships, such as equal corresponding angles and supplementary alternate interior angles.

transversal 2 e1622017102865 — *_{The blue line is a transversal}*

Corresponding Angles:

Corresponding angles are equal. As you can see in the diagram below, the line makes an F shape, which can be back to
