Draw a triangle. Write one of the numbers from 1 to 6 at each corner and one of the numbers along each side (no repeats). Can you arrange them so each side adds up to the same number?
Draw a triangle. Write one of the numbers from 1 to 6 at each corner and one of the numbers along each side (no repeats). Can you arrange them so each side adds up to 12?
Place the numbers 1 to 9 in the circles, such that each side of the triangle adds up to 17
Put numbers 7, 8 and 9 at the corners of a triangle. Now place 1, 2, 3, 4, 5, 6 in twos on each side to make the same total on all three sides (include the numbers at the corners)?
Can you arrange the numbers from 1 to 9 on a tic tac toe board in a manner that the numbers in each row, column and diagonal adds up to 15. Remember that you have to use all the 9 numbers and thus you cannot repeat.
