Geometry - position and direction
Using your knowledge of polygons, you can find the missing points of a shape. Regular polygons have equal length sides and angles. Irregular polygons may also have special properties which will allow you to complete the shape.
A square has four sides of equal length. By using three coordinates, you can find the final coordinate to complete the square.
On the grid below is square ABCDABCDABCD. Find the coordinate of point BBB.
As a square is a polygon the missing coordinate will be five spaces to the left of coordinate AAA and five spaces below coordinate CCC.
Irregular polygons also have special features. The opposite sides of a parallelogram are parallel to each other, which means they go in the same direction.
Find the coordinate which would complete the parallelogram below.
Note: If you extend parallel lines in both directions, they will always be the same distance from each other.
