Part 1
On a math test Ali needs to describe the motions which map ΔEFG to ΔMNO. The coordinates of ΔEFG are ​E(6​,5​), ​F(9​,5​), and ​G(6​,10​). The coordinates of ΔMNO are ​M(0​,0​), ​N(−3​,0​), and ​O(0​,5​). He says there is a translation 6 units to the left and 5 units​ down, followed by a reflection across the​ x-axis. Describe the sequence of rigid motions. What is Ali​'s likely​ error?
