Angles.
Types of Angles.
Angles in a full turn all add up to $\underline{\mathbf{3 6 0}}$
Angles in a half turn all add up to $180^{\circ}$. Note how this is half of a full turn which is half of $360^{\circ}$
Vertically Opposite Angles ( $X$ Angles) are equal. Notice how the angles all add up to $\underline{360^{\circ}}$
Corresponding Angles (F Angles) are equal. Look for the $F$ in the diagrams. The parallel lines are always a good indicator of this.
