Angles

Alternate angles

• 
• The pairs of angles on opposite sides of the transversal but inside the two lines are called Alternate Interior Angles.
• Notice that the pair of alternate interior angles makes a Z
• Alternate interior angles are formed when a transversal passes through two lines. The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.

Corresponding angles

• Corresponding angles are formed when a transversal passes through two lines. The angles that are formed in the same position, in terms of the transversal, are corresponding angles.
• corresponding angles are in the same position. They are both above the parallel lines and to the right of the transversal.
• they are equal
• 

Vertically opposite angles

• 
• Vertical Angles are the angles opposite each other when two lines cross.
• They are always equal.
