Chapter 9 : Basic Polygons
What will you learn in this chapter

Next, we will explore the properties of triangles. We will recognize and list the geometric properties of different types of triangles, which will help us classify them. We will also make and verify conjectures about the sum of interior angles, the sum of interior angle and adjacent exterior angle, and the relation between exterior angle and the sum of the opposite interior angles of a triangle.
Moving on, we will study the properties of quadrilaterals. We will describe the geometric properties of various types of quadrilaterals and classify them based on these properties. We will also make and verify conjectures about the sum of interior angles of a quadrilateral, the sum of interior angle and adjacent exterior angle of a quadrilateral, and the relationship between the opposite angles in a parallelogram.
By the end of this chapter, we will have a solid understanding of polygons, triangles, and quadrilaterals, and be able to apply their properties to solve mathematical problems.
