Use similarity criteria to generalize the definition of sine to all angles of the same measure. / Lesson 4. Students should use a ruler to measure the sides of each triangle, then use trigonometric ratios to determine the angle measurements. Use square root and cube root symbols to represent solutions to equations of the form x = p and x = p, where p is a positive rational number. topics are divided into seven modules and are completed in ten class meetings.
