An angle is the amount of turn between two lines or planes that meet at a common point.
An angle can be measured using a protractor or by using the trigonometric functions sine, cosine, and tangent.
Angles can be measured in degrees, radians, or other units such as gradians or turns.
In a right triangle, the measure of an angle can be found using the inverse trigonometric functions (arcsine, arccosine, or arctangent) or by using the Pythagorean theorem.
Yes, angles can be estimated using other objects such as your fingers or a paperclip, or by using the properties of parallel lines and transversals.
