Triangles, and also pyramids, have been popular designs in construction due to their steady bases. As an example of this, the Trans America building in San Francisco was built in a pyramid shape in the earthquake prone city.
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.
The centre of balance is at the point where the medians of the triangle intersect.

The Romans were popular for their army and their construction!

If the compass angle is changed, the entire geometric shape being drawn is different. For example, if a triangle is being drawn, it could change from an obtuse triangle from a ninety degree triangle.
Draw a base of the required length.

In the proof that the construction creates an equilateral triangle, key reasons include the properties of circles and congruence. When a circle is drawn with a radius equal to the length of one side of the triangle, the points where the circle intersects with the other sides ensure that all sides are equal. Additionally, by applying the congruence of triangles (such as Side-Side-Side), it can be shown that all angles are also equal, confirming the equilateral nature of the triangle. Thus, the construction relies on fundamental geometric principles to establish that the triangle is indeed equilateral.
