A rectangle is a shape that has more than one right angle. A rectangle has four angles, and two of those angles are always right angles, measuring 90 degrees each. This is a defining characteristic of a rectangle, along with having opposite sides that are equal in length and parallel to each other.

Well, honey, a rectangle is the shape you're looking for. It's got not one, but two right angles. So, if you need a shape with a little extra attitude, go for a rectangle - it's got those right angles on lock.
Oh, dude, a rectangle has more than one right angle. It's like, the corners are all, "Hey, look at me, I'm a right angle!" So yeah, if you're into shapes with multiple right angles, rectangles are where it's at.
Obtuse. An acute angle is less than 90 degrees, a right angle is 90 degrees, and an obtuse angle is more than 90 degrees.
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
Right angle. An acute angle is less than 90°. An obtuse angle is more than 90°. If it isn't less than or greater than, it must be equal to. Of course a straight angle is more or less an extreme case of an obtuse angle.
The shape that has 1 acute angle, 1 obtuse angle, and 1 right angle is a scalene triangle. In a scalene triangle, all three angles are different, so it is possible for one angle to be acute (less than 90 degrees), one angle to be obtuse (greater than 90 degrees), and one angle to be a right angle (exactly 90 degrees). This unique combination of angles makes the scalene triangle a versatile geometric shape.
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.
