You are given a square abcd, and midpoints m and n are marked on bc and cd, respectively. draw am and bn, which meet at q. find the size of angle aqb.

Step 1: show triangles ABM and BCN are congruent
 - AB=BC  (sides of square)
 - BM=CN (half sides of square)
 - angle B = angle C (adjacent sides of square are perpendicular)
 => triangles ABM and BCN are congruent (SAS)

Step: find angle AQB
 - angle AQB = QMB+MBQ   (exterior angles of a triangle)
                      = BNC+MBN   (corresponding angles of congruent triangles)
                      = 90 degrees   (exterior angle of triangle BNC)

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
