a geometry teacher asked saul to define "obtuse triangle." saul said that an obtuse triangle is a triangle with one interior angle measure greater than 90â°90â° and two interior angle measures less than 90â°90â°. is saul's definition valid?

This is true. In order to get an obtuse triangle, one angle must be greater than 90 degrees because the definition of an obtuse triangle is an angle measuring greater than the right angle. The other angles must be less than 90 degrees because the sum of the angles must be 180 degrees.

Answer: 900°

good luck on your studies! : )
