vertical angles
the pairs of opposite angles made by two intersecting lines
Vertical angles are a pair of non-adjacent angles formed by the intersection of two lines. These angles are opposite to each other and are equal in size. Vertical angles are formed when two lines intersect, forming four angles. The two angles that are opposite to each other are called vertical angles.
The most important property of vertical angles is that they are always congruent or equal in measure. This means that if one angle measures 40 degrees, the other angle will measure 40 degrees as well.
Another important property of vertical angles is that they are linear pairs. A linear pair is formed by two adjacent angles whose non-common sides are opposite rays. Therefore, two pairs of vertical angles can be formed at the intersection of the two lines.
Vertical angles are used in various areas of math, including geometry and trigonometry, as they help in solving problems related to angles, lines and shapes. It is important to understand these properties so that you can tackle problems involving vertical angles with ease.
