What congruent shape can 2 right-angled triangles make?
Isosceles triangle
What are the shapes that make up the tangram?
2 small triangles 1 med. triangle 2 large triangles 1 parallelogram and a square
Can 2 triangles make a square or a rectangle?
Yes, they can. To demonstrate this draw a square on a sheet of paper. Draw a line diagonally from one corner to the one opposite. Cut along this line and you will have two triangles. Take them apart; if you put them together again in the right way you will have a square. Put together in different ways you can make an isosceles triangle or an equilateral parallelogram. If you do the same thing beginning with a rectangle, you will be able to reassemble the triangles to form a rectangle, isosceles triangle or a (non-equilateral) parallelogram.
Is there a way to make a parallelogram using tangram pieces?
yes,take 2 big triangles.then,take 2 small triangles and a square. first on the right put a triangle facing like a hill.on the left do it the opposite way then put the square in the middle of the 2 triangles and take the 2 small triangles and put them in the middle 2
Is it possible to make a parallelogram out of six tangrams?
The right way. :)
