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.
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.
The other side of the reflex angle will be between 0 and 180 degrees. Measure that angle and subtract the answer from 360 degrees.
