Can you divide the picture shown by drawing 2 straight lines to produce 3 sections, each containing:
Three red “X”s
Two blue “+”s
Draw one line from top center to bottom left corner. Draw second line from top right corner to bottom left corner.
First name the corners form top in clock wise. That means..
Now draw two lines from right corner,2 to bottom left corner,4. And from top corner,1 to the same bottom left corner,4. Now there are 3 sections.
Determine the number of triangles in this picture.
Hint: There are more than 20 triangles.
The sum of each row and column is given! Can you figure out and calculate the value of each shape?
Using only 3 straight lines and without lifting your pencil, can you connect all the dots?
In this picture you can see 6 coins in the shape of a cross. Moving just ONE coin, can you form 2 lines, each with 4 coins?
Nine dots are placed in three rows of each three dots, as shown in the picture. These nine dots must be connected by four straight, connected lines (i.e. without 'lifting up the pen' in between).
