Triangles are used because if you have a triangle you can use the cosine and sine rules. Since you're asking this question you're probably a student all question will be of that form because it's easy for textbooks and teachers.There is also I believe a parallelogram rule but I'm only a student too so i haven't learnt it.
You can create rectangles and squares by combining triangles in specific ways. For example, two right triangles can be arranged together along their hypotenuse to form a rectangle. Similarly, four congruent right triangles can be arranged to create a square by placing them around a central point, ensuring their right angles meet at the corners. This method utilizes the properties of triangles to construct larger, symmetrical shapes.
To calculate the square footage of a quadrilateral, you can divide it into simpler shapes, such as triangles and rectangles, and find the area of each. For rectangles and squares, multiply the length by the width. For triangles, use the formula (base × height) / 2. Finally, sum the areas of all shapes to obtain the total square footage of the quadrilateral.
If you draw your triangles using the centre of the circle as one vertex and two more on the circumference, the area of the circle is approximately equal to the sum of the areas of the triangles; the smaller you make the triangles, the more accurate your result will be.

Yes, the Clifton Suspension Bridge incorporates triangular shapes in its design, particularly in the truss elements and the cable stay structure. Triangles provide structural stability and distribute weight efficiently, which is essential for the bridge's ability to span the gorge over the Avon River. The use of triangles helps ensure the bridge can withstand various forces, enhancing its overall strength and durability.
Architects use triangles as part of their work in designing buildings. And finding the pygratheim therom and stuff.
