Angle Notes: Parallel lines- travel in same direction and will never touch. Transversal – a straight line that crosses at least 2 other lines Complementary angles- add up to 90o, if they are adjacent (sharing a side)- they form a right angle. Supplementary angles- add up to 180o, if they are adjacent (sharing a side)- they form a straight line. Corresponding Angles- When two lines are crossed by another line, the angles in matching corners are called corresponding angles. When the two lines are parallel Corresponding Angles are equal. When two lines are crossed by another line (called the Transversal): The pairs of angles on opposite sides of the transversal but inside the two lines are called Alternate Interior Angles. When two lines are crossed by another line, the pairs of angles on opposite sides of the transversal but outside the two lines are called Alternate Exterior Angles. Same side interior angles are two angles that are on the same side of the transversal and on the interior of the two lines. Same Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary. Vertical Angles are the angles opposite each other when two lines cross. They are always equal. "Vertical" in this case means they share the same Vertex (corner point)
