An angle is considered right if it's measure is exactly 90 degrees.
It is the ratio of the length of the adjacent side to that of the hypotenuse.
Yes. The square is a special form of the angle notation, which specifies a right angle. It is common to put it there, since it clearly defines that triangle as a right-angled and not just a very close one.
If they are a Pythagorean triple then they will form a right angle triangle
The ratio of the side of a right-angled triangle opposite to a specified angle to the hypotenuse; when expressed as a real number between 0 and 1 it defines the sine of the angle
a right angle is a right angle
Because a right angle is a right angle.
A right angle is an angle of 90 degrees.
Assuming your question is what makes a right-angle, it is an angle of 90o .
A right angle is a angle with 90o
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
because a right angle is right and a left angle is wrong
The right angle.
