Question

Fill the magic triangle so that the numbers on each side add up to 10.​

Answer 1

As we know, the sum is 10. In a magical triangle, we have the same sum on each side.
Missing number on the left side of the triangle should be 2,as 5 + 3 + missing number = 10, missing number = 2.
Missing number on the right side of the triangle should be 6,as 3 + 1 + missing number = 10, missing number = 6.
Missing number on the bottom side of the triangle should be 4,as 5 + 1 + missing number = 10, missing number = 4.
