### sense in the lessons

In the Tanakh and Jewish tradition: In Sefer Yetzirah, the twelve diagonal borders are the twelve edges of a cube-like space, which stand for the twelve simple letters. Interpretation: Tradition reads these edges as marking out the six directions, and the world, with their boundaries extending without end. In the primary lessons: A key geometry word: a square and a rectangle each have 2 diagonals, a pentagon has 5, a triangle has none. In everyday life you cut sandwiches diagonally or cross a field diagonally. In chess the bishop moves diagonally. Phrases: diagonal line, draw the diagonal, diagonally opposite.

### note

In maths: the two diagonals of a square are equal and cross at right angles; a diagonal cuts a square or rectangle into two equal triangles; a polygon with n sides has n × (n − 3) ÷ 2 diagonals (hexagon: 6 × 3 ÷ 2 = 9). Sides are not diagonals.

### In the corpora
