Alternate Interior Angles - ∠MAU and ∠OUA ∠HAU and ∠EUA.Yes, it is a MADHOUSE, but can you make sense of it?Ĭan you find the alternate interior angles, alternate exterior angles, and corresponding angles?
Here is a transversal, SD, cutting across parallel lines MH and EO at Points A and U. Corresponding Angles - Angles in the same relative position at each intersection are congruent, shown with the symbol ≅.Alternate Exterior Angles - Angles on opposite sides of a transversal but outside the two parallel lines form supplementary angle pairs.Alternate Interior Angles - Angles on opposite sides of a transversal but between the two parallel lines form supplementary angle pairs.Some figures, such as parallel lines cut by a transversal, create special angle pairs:
Right angles will always be congruent, and any two right angles form complementary angle pairs. They are vertical angles and are congruent.
Looking back at our intersecting lines above, we see that ∠MAN and ∠TAP share a common vertex, Point A, but do not share a common side. They are not adjacent angles because they do not share a common side. When two lines intersect, two pairs of angles opposite each other are formed. Two angle pairs are congruent (have the same measure): Supplementary angles need not be linear pairs. See if you can find the four linear pairs in intersecting lines MAP and TAN: Every pair shares a vertex, the point of intersection, and one common side. Just two intersecting lines creates four linear pairs. Linear pairs always form when lines intersect. Linear pairs are always supplementary and adjacent angles. Linear pairs always share a common vertex and one common ray, line segment, or line. Linear pairs get their name because the sides not common to the two angles form a straight line. These are linear pairs and supplementary angles. Two interesting varieties of angle pairs sum to 180°. Any two angles that sum to 90° are complementary angle pairs:Īny two right angles will always be complementary and congruent, whether or not they share a common vertex or common side. These pairs do not have to be touching to be complementary. Table Of ContentsĬomplementary angle pairs add to 90°. We will look at nine different types of angle pairs.
