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
By using our knowledge of supplementary, adjacent, and vertical angles, we can
solve problems involving the intersection of two lines. Including this one!
Use your knowledge about vertical angles to find missing angle measures.
After completing this lesson, you will be able to identify and draw vertical angles.
You will also be able to state the properties of vertical...
As can be seen from the figure above, when two lines intersect, four angles are
formed. Each opposite pair are called vertical angles and are always congruent.
Note: Vertical angles have a very special quality. They are always congruent to
one another! Check out this tutorial to learn about and see how to identify vertical

We examine three types: complementary, supplementary, and vertical angles.
Definitions: Complementary angles are two angles with a sum of 90º.
Vertical angles are non-adjacent angles formed by a pair of intersecting lines.
You can think of them as the opposite angles that appear in the "bow-tie" formed
