Some structures that use triangles are bridges (such as truss bridges), roofs (like triangular trusses), and architectural supports (like triangular frames or columns) to provide stability and strength.

Are triangles equilateral?

Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.


What is the use of scalene triangle?

Triangles are used in surveying a lot and unfortunately things are rarely the same distance away from a surveyor so scalene triangles are often used to find such distances.More InformationActually, scalene triangles don't have a specific "use." A scalene triangle is simply one in which the three sides are three different lengths. Like triangles in general, scalene triangles connect three points that can describe (or establish) a plane.In land surveying, right triangles are vastly more useful and are generally used to quantify a distance and/or a bearing.


How do you form 8 triangles from 6 sticks?

Use three sticks to form a triangle. Use the other three sticks to form an inverted triangle and place it on top of the first. You will have two large triangles and six small ones - eight triangles in all. The shape is also known as the Star of David.

What shape has three different sized sides?

A three-sided shape is called a triangle. There are three types of triangles: equilateral triangles, iscosceles triangles, and scalene triangles. Equilateral triangles have all equal sides and angles; iscosceles triangles have two congruent legs and a base, and scalene triangles do not have any equal sides or angles.


Which properties of triangles make them special among all other types of polygons?

They are rigid structures: the side lengths determine their shape uniquely. This is one reason that triangles are used in structures - for bracing,

how many straws do you need for triangle based pyrimid?

There are four triangles in the pyramid. The base triangle that supports the other three counts as THREE straws, one per each of the three sides. But the remaining three triangles also use the base triangle for one of their three sides. That means there are only two additional straws for each of the three remaining triangles. So there are SIX straws total in the three triangles supported by the base one. That's a sum total of NINE (9) unique straws in the pyramid...3 in the base and 2 each in the three supported triangles. ANS.
