Problem solving with coordinates 1a) Where should you put point D so that shape ABCD is a square? 2. On this grid, A and B must not move. When C is at (6, 6), triangle ABC is isosceles. D(5,2) b) Where could you put point E so that shape ABCDE is a trapezium? (a) C moves so that triangle ABC is still isosceles. Where could C have moved to? C can move Any point with x = 6 (b) Then C moves so that triangle ABC is isosceles and right-angled. Where could C have moved to? D(4,1) D(6,1) (6,3) or (4,5) or (8,5) to name a few!

The coordinates of A are (4, 4) Mark one point on the grid that has: (4,5) an x coordinate that is equal to 4, and a y coordinate that is greater than 4

7. I am thinking of a point on the dotted grid below. The co-ordinates of my point are (x, y) You have 3 clues to find which of the dots is my point. (a) First clue: x > 0 and y > 0 Which dots cannot represent my point? On the grid below, cross them out like this (b) Second clue: x + y < 4 Which other dots cannot represent my point? This time, put a square around them like this (c) Third clue: x > y What are the co-ordinates of my point? At (1,2) , x < y At (1,1) , y = x At (2,1) , x > y
