If you mean the Mathematic angles, one is that they can all be put together to form shapes.
an acute angle is like a L mashed.
An obtuse angle has its measure between 90 and 180 degrees.
These are some characteristics of equilateral triangle:All the sides of an equilateral triangle are equalIn an equilateral triangle each angle is angle is 60 degree.With an equilateral triangle, the radius of the incircle is exactly half the radius of the circumcircle.
It divides an angle into halves.
it s a angle that is less than 90 degrees.
90o < obtuse angle < 180o
Each angle of a rectangle is a right angle. (90°)
Each interior angle is 140 degrees. Each exterior angle is 220 degrees.
Each angle in a rectangle is a right angle measuring 90°.
um... it is pointy and looks like a house
It is an angle whose measure is between 90 and 180 degrees.
Each exterior angle: 60 degrees Each interior angle: 120 degrees
