I don't really get it plz help tell if it's a regular or not regular polygon
ladessa [460]
So the definition of a regular polygon is that the sides are all equal, the interior angles are all equal, and the exterior angles are all equal.
Notice how with #s 3 and 4, the angles are all shown as equal, as well as their sides. However, #s 5 and 6 have different angles and sides, respectively.
Therefore 3 and 4 are regular, but 5 and 6 are irregular (not regular).

Find the measure of the missing angle.
Zanzabum
34 degrees
The three angles all add up to a straight line, which is 180 degrees. One angle is 56 and one is marked as a right angle, so 90.
56+90+x=180
x=34
