This chapter is nothing short of mathemagical!!! You will begin with a study of square roots of perfect squares (positive and negative roots) and classifying numbers as rational or irrational. From there it will be time to explore the Pythagorean Theorem and seeing how the Theorem leads to The Distance Formula. You will then learn about the Midpoint Formula before spending time with the foundations of similar figures. Similar figures acts as a great connection to special right triangles -> 30-60-90 and 45-45-90 triangles!!! The chapter closes out with a deep dive into trigonometry where sine, cosine, and tangent are learned!! You may have heard of this as SOH-CAH-TOA. Word problems involving angles of elevation and depression cap off an epic chapter of math! Trigonometry sounds scary…but you will see it can be made simple – now go check it all out!!!
