Geometry
What is Geometry?
Geometry is a branch of mathematics that studies the measurements, properties, and relationships found in space, such as points, lines, angles, surfaces, and solids.
The term geometry comes from the Ancient Greek terms geo (earth) and metron (measurement). That is, it was the science that tried to measure everything on Earth.
Geometry has multiple applications in everyday life:

A builder is going to design a building and needs to calculate its volume to obtain a municipal license. To do this, you can use the formula for the volume of a rectangular prism, since the apartment building has that shape.

Geometry is also useful for calculating distances between places. You can calculate the distance from town A to town B.

We have just bought a home. They have told us the square inches it has but we want to calculate them too. As we know that the lot is rectangular, we use the formula for the area of a rectangle to find the square meters of our house, multiplying the width (a) by the length (b).
