A protractor is used to measure angles
It is said to be an irregular figure such as a scalene triangle.
The 7 interior angles of a heptagon add up to 900 degrees
45o and 45o 30o and 60o 20o and 70o, etc...
The 5 angles add up to 540 degrees and each interior angle measures 108 degrees
The three interior angles of every triangle always add up to 180 degrees. If all of them are the same measure, then each one must be 180/3 = 60 degrees.
Supplementary
Yes, vertical angles do have the same measures.
4,140 degrees

The answer will depend on a right WHAT!

Not so sure about angels, butThe sum of the exterior angles of ANY polygon is 360 degrees. The number of sides or vertices, whether the shape is regular or irregular, are irrelevant.
The 5 angles add up to 540 degrees and each interior angle measures 108 degrees
The three interior angles of every triangle always add up to 180 degrees. If all of them are the same measure, then each one must be 180/3 = 60 degrees.
A regular polygon has all the side the same length and the same measures of angels. * * * * * Or measures of angles, even! A concave polygon has at least one angle that is reflex (between 180 and 360 degrees).
150 degrees
