Question

26 classify the triangle as acute, right, or obtuse. 45° 45° a acute b right c obtuse

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is \(180^\circ\).

Step2: Calculate the third angle

Given two angles are \(45^\circ\) and \(45^\circ\). Let the third angle be \(x\). Then \(x = 180^\circ - 45^\circ - 45^\circ = 90^\circ\).

Step3: Classify the triangle

A right triangle has one angle equal to \(90^\circ\). Since this triangle has a \(90^\circ\) angle, it is a right triangle.

Answer:

B. right
