The measure can be anywhere from 91 degrees to 179 degrees. 90 degrees is a right angle and 180 degrees is a straight line.

Does a scalene triangle have 2 obtuse angles also?

It's impossible for a triangle to have 2 obtuse angles. A scalene triangle in one that has no equal angles or sides. It could have 1 obtuse angle or it could have 0.

How many obtuse angles could an isosceles triangle have?

An Isosceles Triangle is a triangle with all angles less than 90o So there are no obtuse angles (between 90o to 180o).

Which angles could form an obtuse triangle?

Any triangle with one angle in the range (90, 180) degrees and the other two angles adding up to its supplement will form an obtuse triangle.

All angles in a scalene triangle are acute?

A scalene triangle could have three acute angles, one right angle and two acute angles, or one obtuse angle and two acute angles.

Has an isosceles triangle have an obtuse angle?

Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.

What is a triangle that has exactly one obtuse angle?

It could be an isosceles triangle providing that the other 2 acute angles are equal otherwise it is just an obtuse triangle

What angles does a obtuse triangle need so it could be a obtuse triangle?

It needs at least 1 obtuse angle. Usually you can only have one obtuse angle, so the rest would be acute.

Can a triangle with two acute angles have to be a right triangle?

Only if its 3rd angle is 90 degrees otherwise it could be an obtuse or an isosceles triangle

All angles in a scalene triangle are acute?

A scalene triangle could have three acute angles, one right angle and two acute angles, or one obtuse angle and two acute angles.

Which triangles have one obtuse angle?

If the triangle has an obtuse angle then the other two angles must sum to less than 900. The triangle therefore CANNOT be an equilateral triangle. It CAN be an isosceles triangle with the two equal angles summing to less then 900. For Example, 1200, 300, 300. It could also be a scalene triangle with angles such as 1200, 500, 100.

What is a Polygon with no acute or right angles?

All obtuse angles is impossible- the sides wouldn't connect. If it has one (the most it could have), it is classified as obtuse _______ (name of polygon ex. triangle, hexagon, etc)

Can a scalene triangle be a obtuse triangle?

Yes, indeed. Imagine a scalene triangle sitting on its longest side. If you could push the pointy part on top down, it would eventually become an obtuse triangle.

A triangle with one obtuse angle could not have congruent angles?

I don't think they can actually. That is kind of a trick question.
