Polygons Box 1 Polygon – A Closed Figure in a plane that has 3 or more sides
4
Polygon Box 2 Concave – A side of the polygon is in the interior.
Convex- No sides of the polygon are in the interior.
5
Polygon Interior Angles (Box 3)
The sum of the measures of the interior angles of a convex n-gon is (n – 2) * 180°
6
Interior Angles Examples
The sum of the interior angles of a convex polygon is 900°. Classify the polygon by the number of sides.
7
Polygon Exterior Angles (Box 4)
The sum of the measures of one exterior angle of each vertex of a convex polygon is 360°

Quadrilaterals and Parallelograms Box 1
Quadrilateral – A four sides polygon Parallelogram – A quadrilateral with opposite sides parallel.
10
Quadrilaterals and Parallelograms Box 2
If a quadrilateral is a parallelogram, then its opposite sides are congruent.

Quadrilaterals and Parallelograms Box 3
If a quadrilateral is a parallelogram, then its opposite angles are congruent.
12
Quadrilaterals and Parallelograms Box 4
If a quadrilateral is a parallelogram then its consecutive angles are supplementary.
