How do you find aras of triangles and parallelograms?
Triangles you use : (base x perpendicular height) divided by 2. Parallelogram: you need to find the area of one of the side triangles, then double it (because there's two of them). Then find the area of the square in the middle, and add this to the area of the two triangles.
What is the formula for a triangular pyramid in surface area?
A=1/2bh The area of a triangle is 1/2bh. If the base of it is a triangle and all 4 of the triangles aren't the same, then you have to find the area of the base triangle and then the three other triangles (which should all have the same area). If all four of the triangles have the same area, then just find the area of one of the triangles and multiply that by four. A triangular pyramid that has four equal triangles is also called a tetrahedron.
How many triangles can a nonagon form from one vertex?
It can form 7 triangles
What are two methods to finding the area of a rectangle?
1 method is to multiply length times the width and the 2 method is to divide the rectangle into triangles and find the area of one of the triangles and multiply the area by two.
What is the formula of a two triangles volume?
There is not one. Triangles are two dimensional, volume is three dimensional, a triangle can therefore have an area but no a volume.
How many squares and triangles form a square pyramid?
One square and four triangles.
How many triangles can be made in an octagon by drawing all the diagonals from one vertex?
You Can Get 6 triangles
A pentagon can be divided into how many triangles by drawing all of the diagonals from one vertex?
3 triangles
How many different triangles there are if one is 50?
Infinitely many.
How many triangles can you make in a 29 sided shape?
Originating from one vertex there are 27 triangles
A pentagon can be divided into how many triangles?
Infinitely many. When you think you have reached the end, just divide one of the triangles into two and you'e got one more. And so on.
How many lines are in 50 triangles that are connected?
The answer will depend on how they are connected: on only one side or more, whether they are nested, whether or not they form a convex tessellated area.
