Type 3-1 Different Types of Magic Squares
Write numbers from 1 to 8 in the without repetition, such that the
sum of the four numbers in each straight line and the sum of the four
numbers on the vertices of each square are equal.
1
8
1 What is the sum of the four numbers in each straight line?
2 For each straight line, the two inner numbers are also the numbers on the
opposite vertices of the small square, and the two outer numbers are also
the numbers on the opposite vertices of the big square. Therefore, if the
sums of the two inner numbers and the sum of the two outer numbers in
each straight line are equal, then the sums of the four numbers on the
vertices of each square are also equal. What is the sum of the two inner
(or outer) numbers?
3 Find four pairs of numbers that have the same sum as 2 . Write the
correct numbers according to the given conditions.
