Question 8

Alternate angles are equal. What are alternate angles?

Answer 8

Alternate angle are inside the parallel lines and opposite sides of the transversal line. Check book or google for picture.

Question 9

Corresponding angles are equal. What are corresponding angles?

Answer 9

Corresponding angles are two angles with one on the inside of the parallel lines and one sitting on the outside. They are both on the same side of the transversal line. Check book or google for picture.

Question 10

How do you find the sum of the interior angles of a polygon.?

Answer 10

To find the sum of the interior angles of a polygon you must subtract 2 from the number of sides in the polygon and multiply your answer by 180. This will give you the sum of the interior angles of a shape.
Sum of interior angles = 180(n-2). N being the number of sides.

Question 11

How do you find the size of the interior angle of a polygon?

Answer 11

First you must find the sum of all the interior angles then divide it by the number of sides.
Size of interior angle = 180(n-2) /n.
