Question

1. draw a picture that shows what vertical angles are. what is always true about vertical angles? vertical angles are always _____________.

Explanation:

Vertical angles are formed when two straight lines intersect, creating pairs of opposite angles. By geometric definition and proof, these opposite angles have equal measure. A diagram would show two intersecting lines, with the opposite (vertical) angles labeled to demonstrate their congruence.

Answer:

Vertical angles are always congruent (equal in measure).

(Example diagram description: Two straight lines intersecting at a point, forming four angles. Label the pair of opposite angles as $\angle 1$ and $\angle 3$, and the other pair as $\angle 2$ and $\angle 4$, where $\angle 1 = \angle 3$ and $\angle 2 = \angle 4$.)
