In summary, an angle is the amount of turn between two lines or planes that meet at a common point. It can be measured using a protractor or by using trigonometric functions. Angles can be measured in degrees, radians, gradians, or turns. In a right triangle, the measure of an angle can be found using inverse trigonometric functions or the Pythagorean theorem. Angles can also be estimated without a protractor by using other objects or the properties of parallel lines and transversals.

Your tick marks appear to be presumptive, rather than secure. What are your thoughts?

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.
