Trisecting this angle means dividing its interior region into three smaller, adjacent angles of equal measure. ## Determine the number of interior rays To divide a single region into three adjacent sub-regions, we must place interior boundary lines. Placing one interior ray divides the angle into two parts (bisection). Placing a second interior ray divides the angle into three parts (trisection). ## Match with the options The two interior rays divide the original angle into three equal angles. Therefore, we need exactly two rays to trisect an angle. This corresponds to option C.

(A) Three

(B) Four

(C) Two

(D) One
