How many degrees does a triangle have?
From 180 degrees to 90 degrees based on my protractor... :D
Is 180 degrees a circle?
No it is a semi circle. Something like a protractor
When you use a protractor to draw an angle that opens to the right degrees should be on the right?
180 degrees
How does finding the degrees of a polygon without a protractor relate to life?
n-4 x 180
How do you figure out the degrees of a triangle without protractor?
Because the 3 interior angles of any triangle add up to 180 degrees.
How do you know that a triangle adds up to 180?
Using a protractor you'll find that the 3 angles of any triangle add up to 180 degrees
Why does a full circle protractor only have 360 degrees?
because a full circle only has 360 degrees
How do you find the area of a triangle which is not 90 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).
How do you name angles?
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.
How do you calculate a reflex angle using a protractor?
The other side of the reflex angle will be between 0 and 180 degrees. Measure that angle and subtract the answer from 360 degrees.
