Question

ear pairs and vertical angles in the diagram, which angles are vertical angles? choose two correct answers. ∠abc and ∠ebd ∠abc and ∠cbd ∠abe and ∠abc ∠abe and ∠ebd ∠abe and ∠cbd

Explanation:

Vertical angles are opposite angles formed by intersecting lines, equal in measure.

• \( \angle ABC \) and \( \angle EBD \): Opposite, vertical.
• \( \angle ABE \) and \( \angle CBD \): Opposite, vertical.

Other options: adjacent (linear pairs or share a side), not vertical.

Answer:

\( \boldsymbol{\angle ABC} \) and \( \boldsymbol{\angle EBD} \), \( \boldsymbol{\angle ABE} \) and \( \boldsymbol{\angle CBD} \) (select the checkboxes for these two options).
