Adjacent and Vertical Angles Concepts

The video tutorial covers vertical and adjacent angles. Vertical angles are formed when two lines intersect, creating pairs of congruent angles across the intersection. Examples are provided to illustrate this concept, showing that vertical angles have equal measurements. The tutorial then introduces adjacent angles, which are next to each other and share a side. These angles form a straight line and are supplementary, meaning their measures add up to 180 degrees. Examples are given to demonstrate how to calculate the measure of adjacent angles using the supplementary property.

What are vertical angles?

• Angles that are across from each other when two lines intersect
