Question

a triangle has angle measurements of 68°, 23°, and 89°. what kind of triangle is it? acute right obtuse

Explanation:

Step1: Recall angle - type definitions

An acute angle is less than 90°, a right - angle is 90°, and an obtuse angle is greater than 90° but less than 180°.

Step2: Analyze given angles

The given angles of the triangle are 68°, 23°, and 89°. All of these angles are less than 90°.

Step3: Determine triangle type

Since all angles of the triangle are acute, the triangle is an acute - angled triangle.

Answer:

acute
