180 is double 90
180 degrees
180 degrees a half of a revolution is a semi circle protractor
From 180 degrees to 90 degrees based on my protractor... :D
No it is a semi circle. Something like a protractor
180 degrees
n-4 x 180
Because the 3 interior angles of any triangle add up to 180 degrees.
A protractor is typically used to measure angles in degrees. It consists of a semicircular or circular scale marked from 0 to 180 degrees (or 0 to 360 degrees in a full protractor). Some protractors also include measurements in radians, but the degree is the most common unit. The accuracy of angle measurement can vary based on the protractor's design and quality.
Using a protractor you'll find that the 3 angles of any triangle add up to 180 degrees
because a full circle only has 360 degrees
with a protractor. or if you don't have one, you can find it using the degrees you already have. The degrees in a triangle should always be 180. So, take the info you have, add it together, then subtract it from 180 (i.e 90+45=135. 180-135=45).
Less than 90 degrees: Acute More than 90 but less than 180: Obtuse More than 180: Reflex Special cases. 90 degrees: Right angle 180 degrees: Line In degrees. Use a protractor to measure angles correctly and accurately.
