What else would need to be congruent to show that ABC PQR by SSS? Given
———-
AC=PR
BC=QR

A. AB=BA

B. AB=PQ

C. AC=PQ

D. A=P

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.
