Acute angle: greater than 0 but less than 90 degrees
Right angle: exactly 90 degrees
Obtuse angle: greater than 90 but less than 180 degrees
Reflex angle: greater than 180 but less than 360 degrees
There are three ways to name an angle, provided there are only three points on the angle. Say the vertex is point A, and there are two rays extending. Each has another point on it, points B and C. You can name this angle BAC, CAB, or A.
by vertex or point
A parallelogram with one right angle has four of them. The name for this figure is a rectangle.
obtuse,cute,right,and straight angles
A 90 degree angle is also known as right angle. A right angle (or 90 degrees) looks like an L shape. A square or rectangle's four corners are all 90 degrees.
Acute, Obtuse, Straight, and Right are the four types of angles.

h
atually it has four of them becausse a right angle is a ninty digrees angle and a rhoumbos is square axcept its side ways so at the end a rhombouse has four right angles
Square.

The VERTEX of the angle is always in the middle... so if it is angle ABC, then you can also name it CBA as long as the vertex letter is in the middle, usually there are only 2 ways to name an angle.Also, if there aren't any other angles with the same vertex, you can just call angle ABC, angle B.Summary: If you have an angle:the vertex is labeled B, the others are A and C. what can you call the angle?Answer: ABC,CBA or B
I would say a square, it has four right angles and four sides.
