Triangles are considered to be the strongest shape because: (A) They won’t change the shape under the application of the force (B) They change the shape under the application of the force (C) They easily stack on top of each other. (D) None of these
Hint: In the given question, we would have to review and recollect the geometry and shape of a triangle and provide a reason to the fact and a common opinion that triangles are considered as the strongest shape among all.
Complete step-by-step answer: In the given problem, we are given the fact that the triangles are considered to be the strongest shape. We know that triangular shape is a polygon which has three sides and three angles. The sum of all the three interior angles is equal to $180$ degrees. The triangle shape is the strongest shape of all as it holds its shape and has a base which is very strong. The triangular shape is dependable and provides support to the overall structure. The triangle is common in all sorts of buildings and supports. So, the triangles don’t change their shape under the application of the force and hence are considered to be the strongest shape of all. Hence, option (A) is correct. So, the correct answer is “Option A”.
Note: The triangular shapes have a very unique property that they are inherently rigid and supportive. No matter how much force we apply to a triangular structure, we cannot change the shape and structure. Other shapes like a square can be molded into a different shape on application of a force.
