True or false? if triangle abc is congruent to triangle def and triangle mno is congruent to triangle pqr then triangle abc is congruent to pqr by transitive property

False.  there has to be a congruent relation between abc and mno for this to be true by the reason of transitive.

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.
