a right angle is half of a straight angle
A straight angle is an angle that is 180 degrees exactly (a straight line). A right angle is 90 degrees (like the corners of a square.)
A right angle because 180* - 90* is 90* which is a right angle !
A straight angle.
A right angle has 90 degrees. A right angle is an angle that bisects the angle formed by the two halves of a straight line.
a right angle is half of a straight angle
Right angle (90) < Obtuse angle < Straight angle (180)
Acute angle=45 degrees Right angle = 90 degrees Straight Angle=180 degrees.
Straight angle
An acute angle is an angle less than 90 degrees. A right angle is 90 degrees. A straight angle is a straight line. For example: take a 90 degree angle and straighten it out to form a line, and it becomes a straight angle.

A straight angle.
A zero angle or a straight angle.
Because then it would not be a right angle. A right angle is 90 degrees. It is straight up and to the right.
A straight angle is 180 degrees so half of that is 90 degrees of a right angle.
You use the right angle next to an acute angle perhaps and you see that when a angle is closer together it is an acute angle and if it is spread apart or farther apart from a right angle it is an obtuse angle. If the angle is a straight line and doesn't look bent like a right angle it is a straight angle.
