Co Interior Angles Are Equal

An equilateral triangle has three sides of equal length.

Co interior angles are equal. 0 0 1. They are supplementary both angles add up to 180 degrees. Solved example for you on related angles question.

The are supplementary angles add up to 180. Alternate co interior and corresponding angles videos. The lines make an f shape.

Angles are equal or congruent to each other when the measurements of the angles are the same. The sum of a pair of co interior angles is always equal to 180 degrees if the two lines are parallel to each other. Any pair of alternate interior angles are equal or co interior angles are supplementary then the two lines are parallel.

24 june learn about alternate corresponding and co interior angles and solve angle problems when working with parallel and intersecting lines. Co interior angles are angles on the same side of the transversal and inside the parallel lines. Two angles on the same side of the transversal in a figure where two parallel lines are intersected by transversal.

When a transversal intersects two parallel lines each pair of alternate interior angles are equal. A co exterior angle is almost the same thing as co interior. When the two lines are not parallel the sum of the two co interior angles would not be exactly 180 degrees.

Co interior angles are not congruent. Conversely if a transversal intersects two lines such that a pair of interior angles are equal then the two lines are parallel. Corresponding angles corresponding angles are equal.
