    so going from Abbey to Kai means we go 2 spots (2 spots)*(30 degrees per spot) = 60 degree rotation

    A taxicab starts at (1, -2) on the grid and picks up a passenger. The taxicab travels a total of 16 blocks, and then drops the passenger off. Which composition of two translations could describe the taxicab’s final position? (x, y) > (x + 4, y - 3), and then (x, y) >(x - 9, y + 1). (x, y) > (x - 4, y + 3), and then (x, y) > (x + 6, y - 1). (x, y) > (x - 3, y + 4), and then (x, y) > (x + 8, y - 1). My answer (x, y) > (x - 3, y + 4), and then (x, y) > (x + 7, y - 1).

    the reflection does not line up with ECD so reflection doesn't work I couldn't get glide reflection to work either

    translation doesn't work either the only thing left is rotation. The only issue is that I'm not sure how they're rotating it. This problem is just odd

    if line p were along BC, then a glide reflection would work but that's not the case since line p is through EC

    "has a scale of 1:40" means that you multiply the smaller dimension (6 inches) by 40 to get the corresponding longer dimension then convert to feet
