Examples:

Classic Triangles and Rerference Angles	Extrapolating data ex.	Co-terminal angles
Find the Sine of 240 ◦ in SRF.	Cos A = ¾ find A to degrees	Find Cos ( 750^0) in SRF	Write Sin( 500^0) in terms of a
	minutes and		positive acute
	seconds		angle

Enduring Understanding (s): ____The relationships between the sides of a right triangle and the Trigonometric ratios.

Essential Question (s): ______What do I do when I can not use a ruler or compass to find the sides or angles in a right triangle?
