Angles formed by opposite rays.
Angles that share a common side and a common vertex, but have no common interior points.
Two angle whose measures have a sum of 90 degrees. or
Two angles whose measures have a sum of 180 degrees. or
Name a pair of vertical angles. Name a pair of adjacent Angles. Name a pair of complementary angles. Name a pair of supplementary angles.
When looking at a diagram, we can conclude: Vertical angles Adjacent angles Adjacent supplementary angles
Angles or segments are congruent Angles are right angles Lines are parallel or perpendicular (unless there are marks that give this information)
Draw two intersecting lines. Number the angles as shown. Use a protractor to measure each angle. Make a conjecture about vertical angles.
If two angles are complementary to the same angle (or congruent angles), then the two angles are congruent.
If two angles are supplementary to the same angle (or congruent angles), then the two angles are congruent.
All right angles are congruent.
