1 INTRODUCTION triangle, you have seen, is a simple closed curve made of three line segments. Note that questions 3 and 5 require using both interior and exterior angle sums in tandem. 7.1 interior and exterior angles answer key class. While this is not the only method for showing the interior angle sum, we find students to be very successful using this approach. Notice when the sides of the angles are adjacent and the vertices meet at one point, they form a straight angle.
Unit 10: Statistics. Before sending students to work on the Check Your Understanding questions, you may need to review the polygon prefixes of hexa-, penta-, hepta-, octa-, nona-, and deca-. Here are six rectangles on a grid. 7.1 interior and exterior angles answer key figures.
