Semester B, we'll
start with right triangles and learn about the trigonometric ratios that come with them. (Don't worry. They don't bite.)box some rectangles, fend off polygons, and make our way around circles.learn about area and volume, which seem like simple concepts, but take up more space than you might think (and not just in your noggin).finish up with some statistics and probability. There's more to it than tossing cubes or flipping cylinders.
P.S. Geometry is a two-semester course. You're looking at Semester B, but you can check out Semester A here.
Unit Breakdown8 Right Triangles and Trigonometry
This unit is all about right triangles, and we hate to break it to you, but it's pretty important. Yeah, the Pythagorean Theorem is essential, and knowing the properties of special right triangles will certainly make your life easier, but none of that compares to what happens after: this unit is where you'll first tackle trigonometry. (Gasp!)
9 Quadrilaterals and Polygons
Quadrilaterals are shapes that have four sides. Seems simple enough, right? Well, not exactly. You might feel comfortable around squares and rectangles, but how much do you know about trapezoids? They're serious wildcards. We'll learn about all the different properties and proofs concerning quadrilaterals, and a few other polygons might sneak their way into the quadrilateral party. We can't blame them. It really is hip to be square.
10 Circles
We'll start by defining the circle and talking about a few of its properties (did you know it owns a mansion in Connecticut and beach house in Boca?). After a little bit about central angles, arc measures, and arc lengths, we'll learn about the equations of circles on the coordinate plane and show circles some love by performing a few constructions with them.
11 Area
As you might have guessed, this unit is all about area. Be ready for a return of triangles, squares, quadrilaterals, circles, and basically every shape we've ever talked about. Once we're finished, don't be surprised if you find yourself secretly calculating areas of soccer fields or road signs in your head. It happens to the best of us.
12 Three-Dimensional Geometry
How much area covers a simple space figure's surface? We've got you covered. How much stuff fits inside a three dimensional solid? We can figure that out, too. In this unit, we'll examine space figures inside and out. We'll stick to simpler solids, such as cubes, prisms, cylinders, and cones. Finding the volume of a tuba is not something we'd like to try right away. Trust us.
13 Statistics and Probability
We're back in the land of probability and statistics, here to pick up some more pearls of wisdom. In this unit, we'll explore frequency tables, "and" vs. "or" probability, and dependent events, as well as factorials, combinations, and permutations. We're hoping that we'll find enough of pearls of wisdom to make a pearl of wisdom necklace, but we'll settle for learning a thing or two instead.
