The plans for a new house include a wall with two triangular windows, ABC and A ′B ′C ′. The vertices of ABC are A (−4, 1), B (−1, 1), and C (−1, 5). The vertices of A ′B ′C ′ are A ′ (−1, −5), B ′ (−1, −2), and C ′ (−5, −2). The architect wants to give a sequence of rigid motions that maps ABC to A ′B ′C ′. Select descriptions and algebraic rules for the appropriate sequence of rigid motions. Rotate ABC by ( )° around the origin, and then translate the image ( ) unit(s) down.
