👉 Learn how to solve for an unknown variable using parallel lines and a transversal theorems. Two lines are said to be parallel when they have the same slope and are drawn straight to each other such ...

An angle is the space between two lines that start at the same point. Angles are measured in degrees (°). They can measure between 0° and 360°. Different types of angles include acute, obtuse, reflex ...

A full turn around a point equals 360º. If a full turn equals 360º, then the sum of the angles around a point must also be 360º. When you calculate angles around a point, you can use this fact to find ...
