(a) True

Because the sum of the angles in a triangle is 180°

Obtuse angle = angle greater than 90°.

180° - Obtuse angle = less than 90°

So there cannot be another obtuse angles, therefore both the other angles will be acute.

A triangle with one obtuse angle must also have two acute angles.a. trueb. false
