Which angles of the parallelogram are greater than a right angle?
One pair of opposite angle is greater than a right angle.
What shape has at least one angle greater than a right angle?
It is a triangle
Which angles in the triangeles have measure greater than a riggt angle?
In general, a triangle doesn't need to have any angle greater than a right angle, but if it does, it can only have one.
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.
Which type of triangle has one angle greater than a right angle?
An obtuse angled triangle, or more simply, an obtuse triangle.
