UNIT 3
PARALLEL LINES
• Lines on the same plane that never intersect
INTERSECTING LINES
• Two lines that have one point in common
PARALLEL PLANES
• Planes that never intersect
PERPENDICULAR LINES
• Lines that intersect to form right angles (90⁰)
SKEW LINES
• Lines on different planes that never intersect
TRANSVERSAL
• A line that intersects two lines at different points
CORRESPONDING ANGLES
• Angles in the same position when two lines are cut by a transversal• Their measures are equal to each other
ALTERNATE INTERIOR ANGLES
• Angles between the parallel lines on opposite sides of the transversal• Their measures are equal to each other
ALTERNATE EXTERIOR ANGLES
• Angles outside the parallel lines on opposite sides of the transversal• Their measures are equal to each other
CONSECUTIVE INTERIOR ANGLES
• Angles that are between the lines on the same side of a transversal• Their sum is 180⁰
