Why can 2 obtuse angles make a right triangle please help
djverab [1.8K]
They can NOT.  A right angle is 90°.  An obtuse angle is greater than 90°.  All the angles in a triangle must add up to exactly 180°.  If two angles are greater than 90° then they will add up to greater than 180, beacuse 90 plus 90 equals 180.  You cannot have a triangle with two obtuse angles because they will add up to greater than 180°.
