Angle Relationships
Term | Definition |
---|---|
transversal | a line that crosses two or more lines, which may be parallel |
corresponding angles | a pair of angles in the same position relative to the parallel lines and the transversal |
alternate interior angles | a pair of angles on opposite sides of the transversal but inside the parallel lines |
linear pair | two angles that are adjacent and supplementary |
same-side interior angle | a pair of angles on the same side of a transversal and between the lines cut by the transversal |
alternate exterior angles/same-side exterior angles | a pair of angles on opposite sides of the transversal but outside the parallel lines |
angle sum | The sum of the interior angles in a geometric shape |
corresponding sides | sides that have the same relative position in geometric figures |
complementary angles | two angles whose measure have a sum of 90 degrees |
exterior Angles | the angle formed outside a polygon when one side is extended |
adjacent angles | two angles in the same plane with a common side, a common vertex, and no interior points in common |
angle | the figure formed by the union of two rays that share a common endpoint |
supplementary angles | two angles who measures have a sum of 180 degrees |
vertical angles | opposite angles formed by two intersecting lines |
