Hello, Trigonometry uses the fact that ratios of pairs of sides of triangles are

functions of the angles. The basis for mensuration of triangles is the right-

angled triangle. The term trigonometry means literally the measurement of

triangles. Trigonometry is a branch of mathematics that developed from simple

measurements.

A theorem is the most important result in all of elementary mathematics. It was

the motivation for a wealth of advanced mathematics, such as Fermat's Last

Theorem and the theory of Hilbert space. The Pythagorean Theorem asserts that

for a right triangle, the square of the hypotenuse is equal to the sum of the

squares of the other two sides. There are many ways to prove the Pythagorean

Theorem. A particularly simple one is the scaling relationship for areas of

similar figures. Read the complete essay here:

Trigonometry - The branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.

You can use trigonometry to help you build the walls of the stadium and make sure they are all at the exact angle.

Trigonometry is a branch of mathematics that studies triangles and the relationships between their sides and the angles between these sides. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves. The field evolved during the third century BC as a branch of geometry used extensively for astronomical studies.[2] It is also the foundation of the practical art of surveying.

trig can be used for meassuring angles or the side length of triangles

using it to build stadiums is easy
