What shape can you make with 4 triangles

Four triangles, similar to the large one, but one third the size. The 4th triangle can be placed on the top of the trapezoid. Three triangles. There are technically many shapes that could be put into the form of a triangle, but only triangles can make real triangles without getting into more complicated shapes.

You can make 6. Four equilateral triangles make up another equilateral triangle. A rectangle and 4 triangles. You can make any triangle, quadrilateral or pentagon with three suitable triangles. Isosceles Tetrahedron. The shapes cosist of: two triangles and three rectangles.

A trapezoid has 2 triangles within it. The answer is five triangles? Log in. Study now. See Answer. Best Answer. What number can you make out of 4 triangles? Study guides. Science 20 cards. Is glucose solution a homogenous mixture. You may only fit long sides to long sides and short sides to short sides.

All the 4 solutions to the four problems do not contain holes in them, nor do they overlap.. If you want the dimensions and angles, its best you contact Halici directly. The T-puzzle, a T shape can be assembled with the four pieces on the left. The T puzzle is a tiling puzzle consisting of four polygonal shapes which can be put together to form a capital T. The four pieces are usually one isosceles right triangle, two right trapezoids and an irregular shaped pentagon.

Kumar Ankit, an engineering student from India, designed and posted this geometric puzzle to Quora, challenging users to find all the hidden triangles in this image nothing goes super-viral like a controversial shape. So, using plastic, paper, card or other triangles, what arrangements can you make with four right-angled isosceles triangles like the ones at the start?

You will have to decide about allowing "flipping over" or not. Like in so many investigations it's good after a while to change a bit of the rule and start again.

So let's say that the four must be joined together BUT you can have them joining with one vertex and all OR part of a side touching. For example the red and orange ones we've already seen above are now allowed: Others might be: Now it's your turn. What arrangements can you find with these new rules? There are at least 9! Students requiring more teacher support can either design the net to make an octahedron 8 equilateral triangles — fold to make a shape like two square based pyramids joined together , or they could be provided with the net to cut out, fold and stick together.

Some nets you can print from the attached files and use are: tetrahedron, octahedron, icosahedron. In other words, a platonic solid is a three dimensional shape where each face is an identical flat shape with all sides and angles the same, and the same number of these faces meet at each corner. There are 5 platonic solids, the cube 6 squares, 3 meeting at each vertex , the tetrahedron 4 triangles, 3 meeting at each vertex , the octahedron 8 triangles, 4 meeting at each vertex , the dodecahedron 12 pentagons, 3 meeting at each vertex , and the icosahedron 20 triangles, 5 meeting at each vertex.

More able students could again be challenged to see how many different objects they can make. Some nets you can print from the attached files and use are: triangular prism, pyramid, pentagonal pyramid, cuboctahedron, truncated tetrahedron, truncated cube, icosidodecahedron.
