Question

triangle angle sum theorem: the three angle measures of any triangle always sum to _.

Explanation:

Step1: Recall the Triangle Angle Sum Theorem

The Triangle Angle Sum Theorem states that for any triangle, the sum of its interior angles is a fixed value.

Step2: State the value

By the theorem, the sum of the three angle measures of any triangle is \(180^{\circ}\).

Answer:

\(180^{\circ}\)
