Question

problem 12: (first taught in lesson 29) complete this sentence by selecting always, sometimes, or never. a right triangle is ________ equiangular. after you pick your answer press go. a. always b. sometimes c. never

Explanation:

Step1: Recall triangle - angle sum property

The sum of interior angles of a triangle is 180°.

Step2: Define right - triangle and equiangular triangle

A right - triangle has one angle equal to 90°. An equiangular triangle has all angles equal, so each angle is 60° ($\frac{180^{\circ}}{3}=60^{\circ}$).

Step3: Analyze the compatibility

Since a right - triangle has a 90° angle, it cannot have all angles equal to 60°. So a right - triangle is never equiangular.

Answer:

C. never
