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.
They are both either bigger or smaller than a right angle
no an acute triangle does not have a right angle. if it had a right angle, it would be called a right triangle. to be an acute triangle, the triangle needs two angles that are smaller than 90 degrees.
No, it cannot be because they are two different things right angle is 90° and obtuse angles are angles greater than 90° Thanks, shanzay
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.
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 acute triangle is a triangle with all angles smaller than a 90 degree right angle.
Angles larger than a right angle and smaller than two right angles (between 90° and 180°) are called obtuse angles("obtuse" meaning "blunt").
They are both either bigger or smaller than a right angle
iscoceles
An equilateral triangle.
I think obtus is smaller than right angle (90°) and acute is bigger.
