Question

a triangle has angle measurements of 25°, 130°, and 25°. what kind of triangle is it? acute right obtuse

Explanation:

Step1: Recall angle - type definitions

An acute - angled triangle has all angles less than 90°. A right - angled triangle has one angle equal to 90°. An obtuse - angled triangle has one angle greater than 90°.

Step2: Analyze given angles

The given angles of the triangle are 25°, 130°, and 25°. Since 130°>90°, the triangle has an obtuse angle.

Answer:

obtuse
