A square with side lengths of 14 units on a square grid. Collaborate slope triangles are related. Tell students they will use their strategies to determine the side lengths of several triangles in the activity. Use special triangles to determine geometrically the values of sine, cosine, tangent for /3, /4 and /6, and use the unit circle to express the values of sine, cosine, and tangent for -x, +x, and 2-x in terms of their values for x, where x is any real number. 4.G.A.1 U08.AO.02 - Right Triangle Trigonometry Practice RESOURCE ANSWER KEY EDITABLE RESOURCE EDITABLE KEY Get Access to Additional eMath Resources Register and become a verified teacher for greater access.
