A triangle is used in construction to make sure something is square or to square something up. A speed square is a small triangular shaped tool used to mark rafter angles. One method to check the square of a room or one wall that is perpendicular to another is to measure 3 feet along one wall and make a pencil mark them measure 4 feet along the other wall and make a pencil mark. Then measure diaganally from pencil mark to pencil mark. If the number is 5 feet the two walls are square to each other.
The following is the answer.
segment bisector
All of the radii of a circle are congruent CPCTC sss triangle congruence postulate
An equilateral triangle is a regular polygon because it has 3 equal sides and 3 equal 60 degree angles that add up to 180 degrees.
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.
The following is the answer.
The centre of balance is at the point where the medians of the triangle intersect.

Triangles are used in construction because they are the most stable structure type. The angles take in weight and spread it throughout the sides of the triangle, so the weight is balanced out.

A triangle is one of the strongest shapes for construction. A square or rectangle can deform into a parallelogram when loaded with weight, but a triangle cannot change shape without breaking one of the sides.
