This unit focused, in part, on relationships in triangles. A triangle is the simplest type of polygon and is frequently used in
construction. Explain why triangles are often used to build bridges, roofs, buildings, and other structures. Which properties of a triangle make it a desirable geometric shape for these applications? Which type of triangle is best? Why is the triangle preferred over other types of polygons? Explain in a paragraph.
The answers are as follows: 1. Triangles are often used to build different types of support structures because of its beneficial properties. Triangles is rigid in shape and it has strength. When force is applied to the side of a triangle, it can not shift into another shape, this is because its sides and angles are fixed. 2. The properties of triangle that make it a desirable geometric shape for building support structures is its fixed sides, fixed angles, rigidity and strength. Triangles are the strongest shapes and they are stable. Thus, triangle can be easily fix together to provide strength and stability over a wide area. 3. There are different types of triangles, these include: equilateral triangle, scalene, isosceles, right triangle, obtuse and acute. Of all these triangles, the best triangle is equilateral triangle. 4. Triangle is preferred over other types of polygon because, it is the strongest. The other polygons can be bent into different other forms that are not regular polygon, but a triangle always retains its shape and can not be deformed.
Answer: Answer below i made it so i wouldnt get copyright hehe
Step-by-step explanation:
Triangles are often used to build bridges, roofs, and other structures because of their shape and the strength it has. The properties of triangle that make it desirable are the fixed angles and sides. Triangles are best because they are stable and strong in many ways. A triangle is preferred over other types of polygon because it is the strongest. Polygons can be formed and bent into different forms although a triangle always stays in its shape and can not be changed, moved or deformed.
an Injective function is a function that maps distinct elements of its domain to distinct elements of its codomain. In other words, every element of the function's codomain is the image of at most one element of its domain.
