Ha ha tricked ya you'll just have to ask a teacher because its hard to explain and i think you mean protractor not porfactor.

if an angle measures 30 then it is acute
the measures of each angle in a dodecogon is 360
An angle that measures 180 degrees would be in a straight line. Therefore, this angle is known as a straight angle.
The interior angle of any regular polygon can be calculated using the formula 180 * (n - 2) / n, where n is the number of sides. In this case, since each exterior angle measures 72 degrees, the interior angle would be 180 - 72 = 108 degrees. So the measures of the interior angles in this regular polygon would be 108 degrees.

An angle that measures 210 degrees is a reflex angle.
The third angle measures 18 degrees.
A right angle measures 90 degrees

An angle that measures 180 degrees is a straight angle, or straight line.Line.
An angle that measures 180 degrees would be in a straight line. Therefore, this angle is known as a straight angle.
An angle that measures to precisely 90o is called a right angle.
The interior angle of any regular polygon can be calculated using the formula 180 * (n - 2) / n, where n is the number of sides. In this case, since each exterior angle measures 72 degrees, the interior angle would be 180 - 72 = 108 degrees. So the measures of the interior angles in this regular polygon would be 108 degrees.
By using trigonometry that is applicable to a right angle triangle.
