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).
What shape has obtuse angles triangle hexagon pentagon or square?
A hexagon or pentagon will have obtuse angles (greater than 90 degrees). A triangle has angles that are all less than 90 and a square has only 90.
Do triangles have at least 2 acute angles?
Yes. The sum of the angles in a triangle is 180° All angles in a triangle must be greater than 0° which means that the sum of any two angles must be less than 180° If two angles are right angles (90°), their sum is 180° which is not less than 180°; thus at most one angle can be a right angle. If one angle is a right angle and another is an obtuse angle (greater than 90°), then their sum is greater than 180°, which is not less than 180°; thus there can be at most one of a right angle and an obtuse angle. If two angles are obtuse angles, their sum is greater than 180°, which is not less than 180°; thus there can be at most one obtuse angle. If there is at most one right angle or an obtuse angle, there must be at least two acute angles.
What shape has all angles greater than 90 degrees?
All the angles in an octagon are obtuse. (Obtuse means greater than 90 degrees.)
What are all the angles that are measure of less than 180 degrees?
Half of them are acute, and half of them are obtuse. There are an infinite number of them altogether.
