Identifying Supplementary Angle Pairs
publish date: 2026/05/16 01:15:6.885916 UTC
In a geometric trapezoid configuration where the horizontal top base segment UV is parallel to the bottom base segment XY, match the upper interior vertices to the placeholder blanks that correctly name their supplementary counterpart angle.
Angle U is supplementary to Angle (1).
Angle V is supplementary to Angle (2).
Correct Answer
(1) X
(2) Y
Explanation
Consecutive interior angles are formed when two parallel base lines are intersected by a non-parallel side line (leg) acting as a transversal. Vertex U and vertex X share the left transversal leg UX, making them supplementary. Vertex V and vertex Y share the right transversal leg VY, making them supplementary.
