How many flat angles is a circumference equal to
One angle equals 360 degrees
A flat angle equals 180 degrees
So one angle equals two angles
How many flat angles is a circumference equal to
One circle angle is equal to two flat angles
What is a right angle equal to? What is a horizontal angle equal to? What is a circumference angle equal to?
A right angle equals 90 °, a horizontal angle equals 180 ° and a circumferential angle equals 360 °
1 circle angle = 2 flat angle = 4 right angle
How many degrees are right angle, acute angle, horizontal angle, perimeter angle and pure angle?
Right angle 90 degrees, acute angle greater than 0 less than 90 degrees, horizontal angle 180 degrees, circumference 360 degrees, obtuse angle greater than 90 less than 180 degrees
