Co interior angles: Co-interior AnglesCo-interior angles are two angles on

Co-interior AnglesCo-interior angles are two angles on the same side of the transversal. They are the inside or interior angles and their sums add to 180. Use the two animations below to explore and test this angle relationship. Additionally, in the first animation, drag around the point "A" to manipulate the drawing. Learn what co-interior angles are, how to use the consecutive interior angles theorem, and see examples and worksheets. Co-interior angles are a pair of angles on the same side of a transversal that are between two intersected lines. Properties Theorems and Proofs Antithesis of the Theorem Co-interior Angles Co-interior Angle Theorem and Proof Solved Examples FAQs Alternate Interior Angles Definition The angles which are formed inside the two parallel lines, when intersected by a transversal, are equal to its alternate pairs. These angles are called alternate interior angles. Co-interior and exterior angles lesson. Theoretical materials and tasks in Mathematics State Board, Class 7.
