Do you know the difference between interior and exterior angles? Consecutive exterior angles posted Dec 1, 2012, 4:24 PM by Ray Kim If parallel lines are cut by a transversal line, then consecutive exterior angles are supplementary. Portable and easy to use, Consecutive Angles study sets help you review the information and examples you need to succeed, in the time you have available. Learn how to define angle relationship. Two time 90 equals 180. So are angles 3 and 5. But, a parallelogram is simply two … consicutive angles:-Angles that occur one right after the other. For a square or a rectangle this is obvious since each angle is 90°. From this definition youll see problems asking you to identify angles that are consecutive interior angles. Therefore, it's a simple use of the properties of parallel lines to show that the consecutive angles are supplementary.. We have already proven that for the general case of parallel lines, a transversal line creates interior angels that sum up to 180°.. adjacent angles:-Two angles in the same plane that share a common side and common vertex. Formally, consecutive interior angles may be defined as two interior angles lying on the same side of the transversal cutting across two parallel lines. The Consecutive Interior Angles Theorem states that the two interior angles formed by a transversal line intersecting two parallel lines are supplementary (i.e: they sum up to 180°). ... the consecutive angles are supplementary. Use your time efficiently and maximize your retention of key facts and definitions with study sets created by other students studying Consecutive Angles. The sum of the consecutive angles is equal to the angle formed by what are the uncommon sides of the angles. Consecutive angles are on either end of the same line segment in a polygon. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.The measure of an exterior angle of a triangle is greater than either non-adjacent interior angle. The consecutive interior angles theorem states that the consecutive interior angles on the same side of a transversal line intersecting two parallel lines are supplementary that is their sum adds up to 180. As seen from the above picture, the two consecutive exterior angles are supplementary because the transversal line cuts the parallel lines. Any parallelogram has consecutive angles that are supplementary. It should be noted that consecutive angles are also adjacent angles: the definition of adjacent angles refers to one side and the vertex shared, but also adds that the other two sides must be opposite rays. Supplementary means that they add up to 180°. Consecutive interior angles are supplementary. The definition of a parallelogram is that both pairs of opposing sides are parallel. Strategy. A trapezoid with nonparallel sides congruent (diagonals are congruent, two consecutive angles are congruent but not supplementary) Definition of a kite (page 290) A quadrilateral in which exactly one diagonal is the perpendicular bisector of the other diagonal.
