Question

13 some triangles can have more than one right angle. a. true b. false reset next

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is $180^\circ$. A right angle is $90^\circ$.

Step2: Analyze multiple right angles

If a triangle had two right angles, their sum would be $90^\circ + 90^\circ = 180^\circ$, leaving no angle for the third vertex. So no triangle can have more than one right angle.

Answer:

B. False
