Tangram puzzles have seven different shapes.
In a tangram, you can create various quadrilaterals using different combinations of its seven pieces. The specific number of distinct quadrilaterals depends on how you define them (e.g., congruent shapes or different orientations). Generally, using just two pieces, you can form at least a few basic quadrilaterals, such as rectangles or parallelograms, but the total combinations can be quite numerous depending on the arrangements. Overall, the creativity in combining the pieces can lead to a wide variety of quadrilateral shapes.
you can make a square with a tan gram eight times or more.
The tangram puzzle consists of seven pieces, known as tans. These pieces are typically cut from a square and can be rearranged to form various shapes and figures. The tans include two large triangles, one medium triangle, two small triangles, one square, and one parallelogram. This simple yet versatile design has made tangrams a popular puzzle for both recreation and education.
