Geometry with sequences of numbers

Numbers using Geometry The next row will have 5 points. How many points will the next triangle have? In Elements it shows numbers in geometric perspective. In previous posts, we saw the product of one natural number by another as the area of ​​a rectangle or square. Property Distributive An example of numbers associated with geometry, we can find triangular numbers.

Quadrilateral

Detectives from all four sides Run your finger along the outline of each figure. Count four sides and four vertices. Draw a grid of 3 by 4 squares: it will have 12 squares. This is an area idea. In the previous post, we talked a little about the book Elements of Euclid, which is made up of 13 books.

Triangles

Introduction In the previous post, we defined polygons and served to define quadrilaterals and their properties. Now, let’s define triangles, for this, we need the concept of polygons. A triangle is a three-sided polygon, in which we use straight segments for the sides. A diagonal of a convex quadrilateral divides it into two triangles. Vertices: can be defined as meeting points between the sides of a triangle. Generally speaking, vertices are meeting points between sides of any polygon. In particular, a triangle is formed by 3 vertices.
