Question

For each tessellation, find the measure of each angle at the circled vertex. Then find the sum of the angles. (just please explain how to do this)

Answer 1

Get a protractor, then find the angle at the circled vertex. Then, find the sum of angles by measuring all of the angles and adding them. Alternatively, use the formula (n-2) *180, where n equals the number of sides, to find the total sum of all angles
