If each interior angle measures 170 then it will have 36 sides
Angles between 90 and 180 degrees are called obtuse.
If one angle is 10 degrees, its opposite angle is also 10 degrees. Since consecutive angles are supplementary, each pair of angles has to add up to 180 degrees so the other angles have to be 170 degrees. Therefore this parallelogram has two 10 degree angles and two 170 degree angles.
An angle that measures 210 degrees is a reflex angle.
The third angle measures 18 degrees.
