it is called Inca
Triangles have three sides while trapezoids are quadrilaterals with four sides. Trapezoids have one set of parallel lines. Triangles do not have any sets of parallel lines.
Because there are 6 triangles in a hexagon, and 3 triangles in a trapezoid, there are 2 trapezoids in a hexagon.
triangles
By cutting through its diagonal and cutting off each corner parallel to its diagonal which will leave you with 2 triangles and 2 trapezoids.
You need at least four triangles, or at least three trapeziums. Or two triangles and one trapezium.
The only way they are both alike as if they a equilateral.
There is not enough information about the triangles to be able to answer the question.
No, trapezoids are quadrilaterals, they have 4 sides. Triangles have 3 sides.
Some shapes that fit that condition are parallelograms, scalene triangles, and trapezoids.
Tangrams
yes it has the same number of lines of symmetry
use 4 triangles, make 2 trapezoids then put them into a hexagon
