Construct an Equilateral triangle with side lengths 2. Drop a vertical line from the top angle to the opposite side creating two Right-Triangles. The altitude will bisect the opposite side since it is an equilateral triangle. Determine the length of the altitude using the Pythagorean Theorem. sin60 =cos60 =tan60 = sin30 =cos30 =tan30 =

This unit is the first part of the second unit for a full-year geometry course that is aligned to the common core standards. It is a unit about triangles that revisits some concepts and procedures students experienced in middle school and also an introduction of new concepts but with an expectation that students will leave with deeper understanding.

All non-calculator, good practice of fractions and decimals. Extensions can include more applied questions, such as how tall is the tree if… Trig B. Motivation: We have found a link between the opposite, adjacent and the angles in a triangle. What about the hypotenuse? We could always use the TSF + Pythag, but that is a bit of a drag.
