One pair of opposite angle is greater than a right angle.
An angle smaller than a right angle - is an acute angle. Larger than a right angle, but smaller than 180 degrees is an obtuse angle. Angles between 180 and 360 degrees are reflex angles.
A right angle measures 90°. There are three angles that have greater measurement than a right angle. They are:Obtuse angles - They are angles that measure between 90° and 180°, but not exactly 90° and 180°. In other words, they measure less than 180° but greater than 90°.Straight angle - It is an angle that measure exactly 180°.Reflex angles - They are angles that measure greater than 180°.
there are 4 angles and normally, there would be 2 angles that are smaller than a right angle Except of cause if the parallelogram is a square or a rectangle, all angles are equal to 90 i.e. right angle
If the other angle is smaller than the right angle, it is an acute angle.If the other angle is the same as the right angle, it is a right angle.If the other angle is bigger than the right angle but smaller than two right angles, it is an obtuse angle.If the other angle is the same as two right angles, it is a straight angle.If the other angle is bigger than two right angle but smaller than four right angles, it is a reflex angle.After four right angles, the other angle starts back at being an acute angle.
An obtuse triangle has 1 angle greater than a right angle and 2 acute angles. Its 3 interior angles add up to 180 degrees.
Acute angles
0 angles
Not really because if one of the angles between two planes is greater than 90 degrees then the other (adjacent) will by smaller.
greater than
In a pentagon, the sum of the interior angles is 540 degrees. A right angle is 90 degrees, so if we consider a scenario where one angle is greater than 90 degrees, it is possible for multiple angles to exceed this measure. However, there can be at most three angles in a convex pentagon that can be greater than a right angle, as having more would exceed the total sum of 540 degrees. Therefore, the maximum number of angles in a pentagon that can be greater than a right angle is three.
a right angle is exactly a 90 degree angle. for example, there are 4 right angles on a square, the corners are right angles. like the edges on papers that is a right angle. an oblique line is smaller than a right angle.
