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 angles, also known as vertically opposite angles, are pairs of angles formed when two lines intersect. Vertical angles have several important properties: Pairs of Congruent Angles: Vertical angles are always congruent, which means they have the same measure or angle size.
The vertical angles worksheet helps students in exploring as to how intersection of lines can result in four linear angles, thereby learning the concept of the supplementary property of angles which are formed by intersecting lines. Download Vertical Angles Worksheet PDFs.
Vertical Angles. Two angles are vertical angles if they are not adjacent and their sides are formed by two intersecting lines. The scissors show two sets of vertical angles. a1 and a3 are vertical angles. a2 and a4 are vertical angles. Two adjacent angles are a linear pair if their noncommon sides are on the same line.
