Because an obtuse angle is greater than 90 degrees by definition and a right angle is 90 degrees by definition, so an obtuse triangle would need to have both a right angle and an obtuse angle, which would exceed the number of degrees than a triangle can have, which is 180 degrees.

No an obtuse triangle cant be a right angle because,a right angle is 90 degrees. a obtuse triangle is over 90 degrees

Why cant you have two obtuse angles in a triangle?

Angle sum property of a triangle states that the sum of angles in any triangle should be 180 degree. An angle greater than 90 degree is an obtuse angle. If we have 2 obtuse angles in a triangle, say, 95 degree, 100 degree & 50, it always tend to violate the angle sum property of the triangle. So we cannot have 2 obtuse angles in a triangle.

Does a right triangle have have one right angle?

Yes there cant be more than one right angle in a right triangle

Why cant a triangle have more than one obtuse angle?

Because the 3 interior angles of a triangle add up to 180 degrees and 2 obtuse angles would be over 180 degrees

Why cant a triangle have more than 1 obtuse angles?

An obtuse angle is greater than 90 degrees; a triangle only has 180 degrees in all three angles (inside angles). two obtuse angles exceed 180 degrees.

Why cant there be a obtuse angle in a right triagle?

A triangles angles must add up to 180 degrees, no more or less

If an angle measures more than 90 then it is an obtuse angle What is the converse of this statement?

its is the differents in the way it is said if its not more than 90 then it cant be obtuse

Is it possible for a triangle to have two right angles?

yes it is possible there are many different ways to draw a triangle the right angled triangle is one of them :) hope i helpedI'm sorry for the previous answer but it is wrong, it is impossible for a triangle to have more than two 90 degree angles. A triangle has 180 degrees in total, so if you have two right angle triangles they would equal 180 degrees and your third angle would have 0 degrees which is impossible.So no you cant have 2 right angles in a triangle
