What does it mean if a number is triangular?
A number is triangular if that number of dots could be arranged into a filled equilateral triangle. It is perhaps easiest to picture with billiard balls in a triangle. Each 'row' of the triangle has one more ball than the row above it, forming an equilateral triangle. The triangular numbers are 1, 3, 6, 10, 15 and so on. The complete set of triangular numbers can be represented by the formula: Tn = n(n+1)/2 Where n is any integer greater than 0.
What is the name of a three dimensional triangle?
Pyramid. Or triangular prism, depending on what exactly you mean.
What does the word triangular mean in maths?
a triangle, a 3 sided figure, a figure with 3 points, etc.
How many corners does a three dimensional triangle have?
First, I'm assuming the by corners, you mean verticies. Second, the answer depends on what you mean by "three dimensional triangle. To some, this could be interpreted as a pyramid. However, I think it is more likely that you are referring to a triangular prism- a prism shape with a triangle as each base. In this case, there are six "corners". Each side has three, where the length-wise edges of the prism intersect the verticies of the triangle. There are three corners on each side, for a total of six. If you really meant a pyramid, then there are five corners.
What does Term mean when using square and triangle numbers?
Each term is a square or triangular number. In the context of the sequence of square numbers, the first term is the first square number, the second term is the second square number and so on.

What is three sided pyramid called?
A triangular pyramid A triangular pyramid has four sides - each of which is a triangle. There cannot be a three sided pyramid. If you mean a 3 sided Pyramid with its base being the forth side it would be a Quadrangle. A four-sided triangular solid is also called a tetrahedron, and two interlaced are called a Star Tetrahedron.
How does each translation affect coordinates of the verticals of the triangle?
The answer depends on what you mean by "the verticals of a triangle".

What goods were imported and exported in the triangular trade?
In history class I learned that the triangular trade traded slaves, beans, cattle, crops, and a lot more things i cannot remember. sorry but i learned this back in 2009 and i have very, i mean very bad memory. -a student
What ia the differences of prism and pyramid?
Well if you mean triangular pyramid and triangular prism then: A triangular pyramid is a geometric solid with a base that is a triangle and all other faces are triangles with a common vertex. A triangular prism is a geometric solid with two bases that are congruent (identical), parallel triangles and all other faces are parallelograms. It is referred to as a right triangular prism if the faces are rectangles.
What is a triangle that has no lines of symmetry?
A triangle having each of its three sides of different lengths is a scalene triangle. That would also mean there are no lines of symmetry.
What does the triangle mean in cycling?
The most common shape for a bicycle frame is pretty much triangular. One main triangle with the bottom bracket, fork and seat post at separate corners. Then there is the rear triangle, with rear Wheel, seat post and bottom bracket at the separate corners.
What does triangle numbers mean?
1 = 1 3 = 1 + 2 6 = 1 + 2 + 3 10 = 1 + 2 + 3 + 4 15 = 1 + 2 + 3 + 4 + 5 this is how we work out triangular numbers. It is the number of dots that when drawn form a triangle The formula for the nth triangular number is n(n+1)/2
