Name the type of angles:
Adjacent anglesTwo angles in the same plane with a common vertex and common side, but no common interior points.
Name the type of angles:
Alternate Exterior AnglesTwo angles that lie outside the two lines on
opposite sides of the transversal.
Name the type of angles:
Alternate Interior AnglesTwo angles that lie between the two lines on
opposite sides of the transversal.
Name the type of angles:
Consecutive Interior AnglesTwo angles that lie between the lines on the same
side of the transversal.
Name the type of angle:
Corresponding AnglesTwo angles that lie on the same side of the transversal & on the same side of the lines.
Name the type of angles:
Exterior AnglesAny of the four angles made by a transversal that are outside the region between the two intersected lines
Name the type of angles:
Interior AnglesAny of the four angles made by a transversal that lie inside the region between the two intersected lines
Name the type of angles:
Linear Pair of AnglesA pair of adjacent angles whose non-common sides
are opposite rays.
Name the type of angle:
Obtuse AngleAn angle that measures greater than 90 degrees and less
than 180°.
Name this figure:
Parallel LinesCoplanar lines that do not intersect and are
equidistant at each point.
Name this figure:
Perpendicular LinesA line is perpendicular to another if it meets or
crosses it at right angles (90°).
Name the type of angles:
Same-side Exterior AnglesTwo angles that lie on the same side of the
transversal on the outside of the lines.
Name the type of angles:
Same-side Interior AnglesTwo angles that lie on the same side of the
transversal on the inside of the lines.
Alternate Exterior Angle Theorem
If two parallel lines are cut by a transversal, then the alternate exterior angles are congruent.
Alternate Interior Angle Theorem
If two parallel lines are cut by a transversal, then the alternate interior angles are congruent.
Corresponding Angle Postulate
If two parallel lines are cut by a transversal, then the corresponding angles are congruent.
Consecutive Interior Angle Theorem
If two parallel lines are cut by a transversal, then the consecutive interior angles are supplementary.
