vertical angles. Adjacent angles always have a sum of . Those Adjacent Angles Are Complementary. Since x and y are supplementary angles (Sum of supplementary angles = 180°). Vertical Angles are the angles opposite each other when two lines cross "Vertical" in this case means they share the same Vertex (corner point), not the usual meaning of up-down. Adjacent angles are a pair of angles that share a common side and vertex. Answer) The angles that are opposite to each other when two lines intersect each other are known as vertical angles. When two lines intersect each other at one point and the angles opposite to each other are formed with the help of that two intersected lines, then the angles are called vertically opposite angles. Any two intersecting lines form two pairs of vertical angles that are opposite to each other. <1 and <2 are NOT vertical.
