For perimeter magic triangles, a simple equation gives the number of magic sums for any given order. Number of different sums = 3 n -5. This even allows for the special ‘case of the two missing sums in the order 4 triangle... The length of each side in triangle DEF is multiplied by the same number, 3, to give the sides of triangle ABC. In general: If two triangles are similar , then the corresponding sides are in the same ratio.

### The 1st step in solving such triangle problems is to count the number of rows and columns in the picture. In this question, there are 4 rows and 3 columns. Now, taking one row at a time - In this question, there are 4 rows and 3 columns.

- Count the Number of Triangle in the Picture below. So were you able to solve the riddle? Leave your answers in the comment section below. You can check if your answer is …
- Notice that the ‘centre’ number approach used for solving triangles in Session 2 can also be applied for other arithmagons. For example, the circle number, 8 in this pentagonal arithmagon can be found by subtracting the box numbers 5, and 9 from the centre number, 22. So for a pentagonal arithmagon, with circle numbers represented successively by c1, c2,… c5, and box numbers represented
- There are two more triangles if the triangle is drawn in a square Secondly, the method is not 81 but rather the number of lines touching the largest triangle multiplied by sides which in this case is 3x9 for three horizontal and 6 diagonal lines.
- The 1st step in solving such triangle problems is to count the number of rows and columns in the picture. In this question, there are 4 rows and 3 columns. Now, taking one row at a time - In this question, there are 4 rows and 3 columns.
