a) Which point is the farthest left?

b) Which point is the farthest up?

c) Which point is horizontally between the other two points?

d) Which point is vertically between the other two points?

Q1

Plot each point below. Connect the points in order, and connect the last point to the first point. Name the polygon formed.

A(-3,4), B(-3,-4), C(5,0)

Q2

a) Write the vector for the translation that moved ABCD TO A'B'C'D'.

b) Write the vector for the translation that would move vertex D to vertex A.

c) Write the coordinates of each image vertex under the translation in part (b).

Q3
