Question

in the figure shown, ∠4 is an exterior angle.
which interior angle is adjacent to ∠4?
∠3
what is another way ∠3 and ∠4 are related?
angles 3 and 4 form a ?
that means m∠3 + m∠4 = ?

Explanation:

Step1: Analyze Angle Relationship

Adjacent angles share a common side and vertex. ∠3 and ∠4 share a side and vertex, forming a linear pair. A linear pair of angles is supplementary, meaning their measures sum to \(180^\circ\).

Step2: Identify Angle Type

Angles 3 and 4 form a linear pair. Supplementary angles sum to \(180^\circ\), so \(m\angle3 + m\angle4 = 180^\circ\).

Answer:

Angles 3 and 4 form a linear pair. \(m\angle3 + m\angle4 = 180^\circ\)
