Question 1

How do you calculate the exterior angle of a shape?

Answer 1

360 over n (n being number of sides)

Question 2

How do you calculate the interior angle of a shape?

Answer 2

180x(n-2) over n (n being number of sides)

Question 3

Interior angle + exterior angle always = to _______ fill in the blank

Answer 3

180

Question 4

How do you find out the number of sides in a polygon?

Answer 4

360 over exterior angle

Question 5

If the sum of interior angles in a polygon add up to 3060. How many sides are there?

Answer 5

If 180x(n-2) = to 3060
Then = 3060 over 180 which equals to 17
Therefore 17+2 = number of sides
Because of the extra (n-2) which has been turned around into (n+2)
