How many triangles can make a hexagon?
4 triangles make 1 hexagon. (easy way to find out how many triangles there are in a polygon- take number of sides of the polygon, subtract 2 from it, that's your answer!)
Can 2 triangles make a square or a rectangle?
Yes, they can. To demonstrate this draw a square on a sheet of paper. Draw a line diagonally from one corner to the one opposite. Cut along this line and you will have two triangles. Take them apart; if you put them together again in the right way you will have a square. Put together in different ways you can make an isosceles triangle or an equilateral parallelogram. If you do the same thing beginning with a rectangle, you will be able to reassemble the triangles to form a rectangle, isosceles triangle or a (non-equilateral) parallelogram.
Why is a square a rectangle but a rectangle is not a square?
a rectangle doesn't have four equal sided measurements, which is the definition of a square. also it can take one or more squares to make a rectangle but u can't make a rectangle into a square.
How many triangles does a 20 sided polygon contain?
it would have 18 triangles because u take 2 away each time.
How many lines of symmetry do rectangles have?
Its 4 just like a square * * * * * No it is not. The diagonals of a square are lines of symmetry; not so with a rectangle. So there are only 2 lines of symmetry. In theory, the statement made by the User above^^^ is true, but when it comes to the decisive moment where one has to create structures, or anything that might save or take away lives, that fails... In a rectangle, if you make diagonals, the rectangle will be split into 2 equal length, equal size, right triangles. These people have made the common misconception of trusting a textbook entirely for their answers. Textbooks are written by humans, and humans make mistakes. If everyone understood this, 9/11 never would have happened.
How many triangles does it take to make a decagon?
10 triangles
How many triangles does it take to make a nonagon?
7
How many triangles does it take to make a undecagon?
Nine, as a n-gon can be cut in n-2 triangles.

Can you make a trapezoid with triangles?
Yes, you can but it take 3 triangles.
How do you calcuate the diagonal of a rectangle?
Since a diagonal divides a rectangle into two triangles, this is actually a problem in trigonometery. Since a rectangle has right angles, the resulting triangles also have right angles, therefore you can apply the Pythagorean Theorem. Or, just take your ruler and measure the diagonal. That's the direct approach.
How many triangles does it take to make a rectangular prism?
4, one for each side face
How many triagles would it take to make a parallelogram?
It needs only 2 triangles to construct a parallelogram
How many triangle doese it take to make a rhombus?
2 triangles make up a rhombus which has 4 interior angles adding to 360 degrees and a triangles has 3 interior angles add up to 180 degrees. Therefore: 360/180 = 2 triangles
What total angle measures always equal 360 degrees?
Circles measure 360 degreesAny quadrilateral as well.Try to picture this, if you take a rectangle, and make a diagonal line across it, you have two triangles. Triangles will ALWAYS measure up to 180 degrees, so since you have two, 180X2=360
Why is a square a rectangle but a rectangle is not a square?
