Question

what kind of triangle is this?
acute right obtuse

Explanation:

Step1: Recall triangle type definitions

An acute triangle has all angles less than \(90^{\circ}\). A right triangle has one angle equal to \(90^{\circ}\). An obtuse triangle has one angle greater than \(90^{\circ}\).

Step2: Check given angles

The given angles are \(50^{\circ}\), \(47^{\circ}\), and \(83^{\circ}\) (since \(50 + 47+83=180\)). All \(50^{\circ}<90^{\circ}\), \(47^{\circ}<90^{\circ}\), \(83^{\circ}<90^{\circ}\).

Answer:

acute
