Geometry and Coordinates
(a) Write down the coordinate of point B.

(b) Write down the coordinate of point A.

(c) Plot and write down the coordinate of point D, so that ABCD is a rectangle.
Coordinates Bingo
Draw yourself a 3 x 3 bingo grid. Write down any of
the coordinates you see on the Cartesian grid into your grid.
Using coordinates
Find the three pairs of coordinates that can be plotted to create a square:

A: (....... , .......)
(....... , .......)
B: (....... , .......)
(....... , .......)
C: (....... , .......)
(....... , .......)
Using coordinates
Find the three pairs of coordinates that can be plotted to create a square:

A: (2 , 5)
(-2 , 5)
B: (2 , -2)
(-2, 2)
C: (0 , 4)
(0, 0)
Main Activity 1
