How do you know an angle is greater than or less than a right angle?

Answer: It depends on angle number, like 4 is more than two while one is lesser than two

Step-by-step explanation:

A right angle is 90 degrees, therefore anything higher (ex:130degrees) is bigger and anything lower (45 degrees) is less, an acute angle is lesser while and obtuse is more

if the angle is greater than 90°for example 120° we call it an obtuse angle while the angle 30° is less than 90° so it's an acute angle
