In this chapter, students will use concepts from their study of triangles and quadrilaterals to develop area formulas, ﬁrst for quadrilaterals and then for regular polygons and circles. Special area formulas will be derived for parallelograms, rhombuses, trapezoids, and kites. Students also examine the ratios of the perimeters and of the areas of similar ﬁgures. Finally, students will consider arcs and sectors of circles and apply their areas to geometric probability.
- You will learn how ﬁnding the area of a rectangle can help you ﬁnd the areas of parallelograms and triangles.
- You will learn how to ﬁnd the areas of special quadrilaterals and regular polygons.
- You will learn how perimeters and areas of similar ﬁgures are related.
- You will also learn how to ﬁnd measurements of parts of circles.
