Describe a method for verifying that quadrilateral EFGH is a parallelogram if only the interior angle measures of EFGH are known. Explain your answer.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

Using the rise/run rule. you would get 2/6.simp. 1/3
