Regardless of how wide you open or close a pair of scissors, the pairs of adjacent angles formed by the scissors remain supplementary. If the transversal cuts across parallel lines (the usual case) then exterior angles are supplementary (add to 180°). The two pairs of alternate interior angles formed are: ∠1 and 2 ∠3 and ∠4; Thus ∠1 = ∠2 and ∠3 = ∠4. This is true for all exterior angles and their interior adjacent angles in any convex polygon.

Below, angles FCD and GCD are supplementary … Learn about Alternate Exterior Angles: When two lines are crossed by another line (called the Transversal), Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal. If the two angles of one pair are congruent (equal in measure), then the angles … When a line L1 is cut by a transverse line L2, 4 angles are formed. Parallel lines are very useful in designing the structure of various plots, buildings, bridges, and roads. The two pairs of angles that are on the same side of the line L1 are called supplementary angles, since their sum is … Understand: That angles can be classified by their location of intersection.
