How many triangles and rectangles are need to make a triangular prism?
2 triangles and 3 rectangles
How many triangles and trapezoids make a hexagon?
You need at least four triangles, or at least three trapeziums. Or two triangles and one trapezium.
How can you make a trapezoid with triangles?
You need 3,5,7,9... triangles. They have to be equilateral triangles. 1,3,5,7... need to be upside down while 2,4,6,8... have to be right side up. ______ /\ /\ /\ / \ / \ / \ /__\/__\/__\ I know, bad picture, hopefully you get the point though.
What shapes do you need to make a hexagonal pyramid?
2 hexagons and six triangles
how many triangles are there in a cone?
An infinite of infinitely small ones. You would need to use calculus to calculate the volume of a cone given a single triangular cross-section.

How do you make a square out of tangrams?
First you put both of your big triangles together to form a bigger triangle which is eventually half of the square and then to make the other half you you need to put one of your small triangles in the middle so that the point of it will be touching the point of the bigger triangles you put in be also the side of your small triangle will need to be on the triangle that your havingbe your bottom and then you get your small square and and put it against the other side of the small triangle but also on the big triangle that is going to be the side of the square and then put your other small triangle against the small square but put it upside down so that there will be part of the top and then put your parrellelogram upright by the small triangle that has its point by the big triangles and then last but not least put your last small triangle in the corner to finish the top and side of your square.this is one way you can make a square out of tangrams.but there is seven more not counting this way.
Who do you draw the hourglass?
To draw an hourglass, you need a piece of paper. Next you need to draw two vertical lines of the same length. After that, draw the horizontal lines connecting the vertical lines. When that is done, you need to draw two triangles overlapping themselves. Make small curves at the top, middle and bottom. Make the triangles slightly curved, then erase the original triangles. Color in the bottom and top to the three curved lines. You have an hourglass, but to make it more interesting, draw two short straight lines on the top and two small straight lines on the bottom. HOURGLASS!

How many triangles in a triacontakaidigon?
A triacontakaidigon is a polyhedron with 32 sides. If the sides are all triangles, then there are 32 triangles in a triacontakaidigon, but a triacontakaidigon does not need to have triangular shaped sides.

How many triangles does a dodecahedron have?
A dodecahedron need not have any triangular faces.
How many short isosceles triangles are needed to build one great Icosahedron?
According to some definitions an icosahedron is considered a Platonic solid so that each of its faces is an equilateral triangle. You would, therefore need three coplanar isosceles triangles to make each face of the icosahedron. Since there are 20 faces in an icosahedron, you would need 60 such triangles.
