Question

classify the triangle using its angles. acute right obtuse

Explanation:

Step1: Recall triangle classification by angles

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: Analyze the given triangle

From the visual (assuming the triangle has one angle greater than \(90^{\circ}\) as per typical obtuse - triangle appearance in such problems), we check the angle measures conceptually.

Answer:

obtuse
