Angles Opposite Interior Definition

Illustrated definition of alternate interior angles: when two lines are crossed by another line (the transversal), a pair of angles on the inner side of each. Those angles are known as interior or exterior angles. alternate angles are shaped by the two parallel lines crossed by a transversal. consider the given figure, ef and gh are the two parallel lines. rs is the transversal line that cuts ef at l and gh at m. if two parallel lines angles opposite interior definition are cut by a transversal, then the alternate angles are equal. Because an exterior angle is equal to the sum of the opposite interior angles, it follows that it must be larger than either one of them. stated more formally: theorem: an exterior angle of a triangle is always larger then either opposite interior angle. drag the vertices of the triangle around to convince yourself this is so.

For a complex quadrilateral, interior angles add to 720° because two of the interior angles are reflex angles, each greater than 180° but less than 360° diagonals of a quadrilateral all convex quadrilaterals have diagonals (line segments connecting non-adjacent vertices) inside their enclosed space. The angles formed at the outside or exterior side of the two parallel lines with a transversal. ∠p = ∠z and ∠q = ∠y: consecutive interior angles/co-interior angles: the angles formed inside the two parallel lines but one side of the transversal is the consecutive interior angles. the angles are supplementary to each other, that means.

With each pair of alternate interior angles, both angles are inside the parallel lines and on opposite (alternate) sides of the transversal. there are thus two pairs of these angles. in the figure above, click on 'other angle pair' to visit both pairs of alternate interior angles in turn. remember: interior means inside the parallel lines.
