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.

What are reasons used in the proof that the equilateral triangle construction actually constructs an equilateral triangle triangle?
The following is the answer.
Which type of construction is used to construct a triangle point of balance?
segment bisector
What are reasons used in the proof that the angle-bisectors construction can be used to bisect any angle?
All of the radii of a circle are congruent CPCTC sss triangle congruence postulate
Are reasons used in the proof that the equilateral triangle construction actually constructs an equilateral triangle Check all that apply.?
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.
Why are triangles used in the construction of bridges?
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.
