A triangle with coordinates (1, 1), B(4, 2). C1(3, 5) is translated three units down and five units to the left. What are the coordinates of the new triangle?

Your answer should be B.

Explanation: Moving left or right affects the x coordinate, and moving up or down affects the y coordinate.

Moving 3 units down: A(1, 1 - 3), B(4, 2 - 3), C(3, 5 - 3) = (1, -2), (4, -1), (3, 2)

Moving 5 units to the left: A(1 - 5, -2), B(4 - 5, -1), C(3 - 5, 2) = A(-4, -2), B(-1, -1), C(-2, 2)

(Sorry I said A, earlier.)

19.side- angle- side

20. angle- side- angle

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
