Basic Geometry Concepts and Algebra 4 CHAPTER Math at Work: Interior Designer Jamie Callum walks into a room and sees possibilities. She immediately starts imagining pictures on the walls, rugs across the fl oor, lights hanging from the ceiling. As an interior designer, her job, in her words, “is to make spaces comfortable, beautiful, and functional.” Jamie grew up reading fashion and architecture magazines. What she never expected, however, was how much math interior design would require. “I couldn’t do my job without geometry,” Jamie explains. “I have to account for the angles of walls, the perimeters of rooms, and which furniture should be parallel and perpendicular to the walls. Math helps me bring my creative ideas to life.” Jamie’s combination of mathematical skill and creative inspiration has enabled her to design the interiors of homes, restaurants, and offi ces. Interior design, Jamie explains, is ultimately a series of decisions. “Every room is like a blank page,” she describes. “You have to choose how to fi ll that page. But I have to listen to what my clients need, what they want, and determine what is possible. So it is very important for me to be a good listener and to take good notes so that when I go back to the offi ce, I can design something my client will love.” In this chapter, we will explore geometry, the math of angles, lines, and shapes. We’ll also discuss some ways to become better note-takers. 281 OUTLINE Study Strategies: Taking Notes in Class 4.1 Introduction to Geometry 4.2 Rectangles, Squares, Parallelograms, and Trapezoids 4.3 Triangles 4.4 Volume and Surface Area Putting It All Together 4.5 Solving Geometry Applications Using Algebra Group Activity emPOWERme: Active Listening
