Description: transversal lines
Image copyright: my own creation 2009 made in paint
Adjacent angle- angles next to each other
Alternate exterior angle- a pair of parallel lines intersected by a transversal (outside angles)
Alternate interior angle- a pair of parallel lines intersected by a transversal (inside angles)
Vertical angle- pair of angles directly opposite of each other
Acute angle- angle measures less than 90 degrees
Obtuse angle- angle measures more than 90 degrees
Right angle- angle measures exactly 90 degrees
Transversal- a line that cuts through two or more lines
Angle- two rays that start at the same point
Parallel- two lines that will never intersect
Perpendicular- two lines that intersect at a 90 degree angle
KEY:
Parallel lines AB, CD
