Answer At every congruent side, the two triangles can be joined in two ways. There are three sides in each triangle which are congruent to three sides of the other triangle. 2 x 3 = 6. Hence there are six shapes that can be formed. The shapes will be 2 isosceles triangles, a kite, two parallelograms, a rectangle If it's an isosceles right triangle, then the there are two shapes that can be formed by joining the bases and one shape by joining the hypotenuse. Again 2*3/2!
