Geometry H Mrs. Diaz NAME:______________________________________ DATE:______________________________________ UNIT 7 ASSIGNMENT #3 Introduction to Polygons and Interior Angle Sum OBJECTVE: S.W.B.A.T. find the measurement of each interior angle of a REGULAR polygon DIRECTIONS: Use what you know about interior angles to find the value of x. The Polygon Angle-Sum Theorems Use a word from the list below to complete each sentence. concave equilateral polygon regular polygon regular polygon convex exterior angle equiangular polygon interior angle 1. A polygon that has an interior angle greater than 180° is a __________ polygon. 2. A polygon that has no interior angles greater than 180° is a ___________ polygon. 3. A hexagon in which all angles measure 120° is an example of an ________ . 4. An octagon in which all angles measure 135° and all sides are 6 cm long is an example of a _______________ . 5. An angle inside a polygon is an __________ GROUP PRACTICE DIRECTIONS: Use the rule you found with your group, to find the interior angles of the given polygons 1.
