Vertical angles theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other. Let's learn about the vertical angles theorem and its proof in detail.

Vertical Angles Worksheets. When two lines intersect, two pairs of congruent angles are formed. Our printable vertical angles worksheets for grade 6, grade 7, and grade 8 take a shot at simplifying the practice of these congruent angles called vertically opposite angles.
(Vertical Angle Theorem) Let A, B, C, D be four distinct points in the plane such that the betweenness relations A∗X∗C and B∗X∗D are valid. Then the measures of the vertical angles satisfy |∠AXB| = |∠CXD|. Proof. Two applications of the Supplemental Angle Identity (the sum of their measures is 180. degrees) imply that. and if we subtract.
Whenever two lines intersect, two pairs of vertical angles are formed. We are allowed to assume vertical angles from the diagram. Vertical Angles Theorem: Vertical angles are congruent.
