Vincent drew a line from one coner of a rectangle to another corner to make 2 triangles describe the 2 triangles he made?
Inscribed triangles in a rectangle are identical right triangles but they are rotated 180 relative to each other.
How are the areas of the triangle and rectangle related?
the area of a triangle is half that of a rectangle made using two of those triangles.
Can all 4 sided shape be made by two right angled triangles?
Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.
How do you make a rectangle with 2 triangles and two squares?
Draw a rectangle made with three squares. Then put a diagonal line through the center one. Tah-Dah
What shape is made up from 4 triangles?
It would depend on the triangles, but assuming they were equilateral or isosceles, a trapezoid if alternated in a line.
Is a rectangle made up of congruent shapes?
I think a rectangle is NOT made up of congruent shapes because it only does not have triangles.

Platonic solids is made from triangles?
No. Platonic solids, as their name suggests, are 3-dimensional objects. A triangle is 2-dimensional.

Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.
What shape is made out of two right triangles?
Two right triangles, when joined together by their hypotenuses (the side opposite the right angle), will form a rectangle.

What shape is made out of two congruent triangles?
If you have 2 EQUILATERAL triangles, and you stack them on their respective hypotenuses, the result: SQUARE. If you have 2 ISOSCELES triangles, and you stack them on their respective hypotenuses, the result: RECTANGLE. If you have 2 OBTUSE triangles, and you stack them on their respective hypotenuses, the result: PARALLELOGRAM.
Can anyone give a brief explanation of the Five Platonic Solids?
The 5 are: the tetrahedron, made up of four triangles the hexahedron, made up of 6 squares (this solid is also known as the cube) the octahedron, made up of 8 triangles the dodecahedron, made up of 12 pentagons the icosahedron, made up of 20 triangles at each vertex on these solids, there are an equal number of faces meeting they are all regular polyhedra for each solid, the angles and sides are congruent and if it wasn't obvious already, they were discovered by Plato anything else?
Do the four triangles made to form a rectange have the same area?
Not necessarily. All one can say about "any rectangle" is that the opposite triangles are of equal areas.... that does not mean that adjacent ones do. So, in a rectangle ABCD, with diagonals which cross at E ABE = CDE and ADE = BCE but ABE may not be equal to ADE
What are the three types of polygons that can be the faces of a Platonic solid?
The polygons are the equilateral triangle, the square, and the regular pentagon. The faces of these platonic solids are made from the following polygons: tetrahedron - 4 triangles cube - 6 squares octahedron - 8 triangles dodecahedron - 12 pentagons icosahedron - 20 triangles
