An opposite angle, also known as a vertical angle, is formed when two lines intersect. These angles are directly across from each other and share a common vertex but are not adjacent.
Opposite angles are always congruent, meaning they have the same measure. In geometry, they play a crucial role in various theorems and proofs.
Understanding opposite angles is fundamental to exploring the relationships between intersecting lines, angles, and geometric properties, providing insights into the symmetry and balance of geometric figures and shapes.
