Question

question 2 of 10
a triangle with one obtuse angle must also have two acute angles.
a. true
b. false

Explanation:

The sum of the interior angles of a triangle is \(180^{\circ}\). An obtuse angle is greater than \(90^{\circ}\). If there were another non - acute (i.e., right or obtuse) angle, the sum of the angles would exceed \(180^{\circ}\). So, the remaining two angles must be less than \(90^{\circ}\) (acute).

Answer:

A. True
