Vertical Angles Vertical angles are formed by the intersection of two lines and share a common vertex point. Vertical angles are congruent to one another. Angles A & B are vertical angles. A B Photo: 78 Peachtree Circle Pottstown Dining Room Table Top 10/22/12
Consecutive Interior Angles Consecutive interior angles are on the same side of the parallel lines and the same side of the transversal. Consecutive interior angles are supplementary angles (their sum is 180 degrees. Angles A & B are consecutive interior angles. A B Photo: 78 Peachtree Circle Pottstown Banister 10/22/12
Alternate Interior Angles D Alternate interior angles are between the parallel lines and on opposite sides of the transversal. Alternate interior angles are congruent to one another. Angles A & B and C & D are alternate interior angles. B A C Photo: 78 Peachtree Circle Pottstown Broomstick over front sidelight 10/22/12
Alternate Exterior Angles Alternate exterior angles are outside the parallel lines and on opposite sides of the transversal. Alternate exterior angles are congruent to one another. Angles A & B and C & D are alternate exterior angles. C B A D Photo: 78 Peachtree Circle Pottstown Grand Piano Strings and Hammers 10/22/12
