Question

a triangle has angle measurements of 36°, 66°, and 78°. what kind of triangle is it? acute right obtuse

Explanation:

Step1: Recall triangle types

An acute triangle has all angles less than \(90^\circ\), a right triangle has one \(90^\circ\) angle, and an obtuse triangle has one angle greater than \(90^\circ\).

Step2: Check each angle

The angles are \(36^\circ\), \(66^\circ\), and \(78^\circ\). All are less than \(90^\circ\).

Answer:

acute
