Hey there! :)
A right angle is a shape of a square. This angle is a bit wider. That means it's greater than 90° and less than 180° because it isn't a straight line.The only type of angle like that is an obtuse angle.
Acute = Less than 90°
Right = Equal to 90°
Obtuse = Greater than 90°
Straight = 180°
The answer ⇒ Obtuse angle
Hope this helps :)
