What is an acute angle?
In GCSE maths, an acute angle is an angle formed between two lines that is greater than 0° and less than 90°.
An acute angle is smaller than a right angle. If two straight lines cross each other then there will be two pairs of equal angles. All four angles could be right angles; otherwise, one of the pairs will be acute angles.
