Question

practice
write a conjecture about each geometric object described. draw examples to test y
a. vertical angles

enter the answer in the space provided.

Explanation:

Vertical angles are formed when two lines intersect, creating opposite pairs of angles. A conjecture about them is based on observing their measures in examples (e.g., intersecting lines forming 40° and 140° pairs, where opposite angles are equal).

Answer:

If two lines intersect, then the vertical angles formed are congruent (have equal measures).
