► Because it remains rigid. there is only one way to connect 3 lines into a triangle (think about beams and connectors). the structural strength comes from the beams and the connectors. the strength of the connectors is needed to keep the beams together, but the real strength comes from the beams. as long as they don't stretch/shrink, the triangle will be stable.
for a rectangle, the same beams/connectors could be used for a parallelogram. all of the structural strength would have to be in the connectors. if the beams are allowed to pivot at the corners, you will loose the structure
Mostly congruent triangles are used for construction of things like bridges and buildings because they are considered more stable and strong to use (i hope that helps i had to learn this for a project)
Triangles are used in structures because a triangle is a very stable shape that cannot be stretched or squashed easily - unlike rectangles which can easily become parallelograms.
Architects use triangles as part of their work in designing buildings. And finding the pygratheim therom and stuff.
You can prove that to triangles are congruent with SSS, then use CPCTC to prove that two corresponding angles of those triangles are congruent.
The geometric shape formed by connecting the perimeter of five points is a pentagon. Its basic construction is that of three triangles with one triangle in the middle sharing two of its sides with a base line of the other two triangles. The maximum number of triangles that can be created, if you count only those triangles that are formed by line segments between each of the five points, are ten (10).
Triangles are rigid, quadrilaterals are not - a square can be "squashed" into rhombus.
Urban construction engineers are likely to use concrete, steel, and glass.

There are many types of materials engineers use to build walls. Three possible construction materials are wood, brick, and concrete.
Construction engineers would be employed in areas of construction. They can be managers, product control managers, supervisors and possibly even work on construction sites.
NO!!!! Only to right angles (90 o) triangles. For other types of triangle, you have to use a construction line, which has a right angle in it.
Trigonometry is used to define triangles, but it is also useful in the representation of waves. Sound engineers, obviously, use deal with sound waves. The pitch, volume, and direction of a sound wave are all deeply rooted in trigonometry.

i think because of the shape.

Depends. People that develop explosives are Chemical Engineers. People that design the USE of explosives may be Civil Engineers, or Mining Engineers. However, many everday users of explosives for mining and construction do not have a degree.
