Geometry (Class 75)
Lesson Title
CST Geometry Part 1
Overview
The opener for today is a partner challenge focusing on knowing the code names (sine, cosine, tangent) for the three main trigonometric ratios. Students then will take the first part of the Geometry CST. In the time they have left after the test students will be continuing their work on the trigonometry practice problems.
