How to Choose the Right Triangle for You

Your Guide to buying the best Triangles


This buying guide is designed to help you make an informed decision when purchasing a triangle. It covers the different types of triangles available, their materials, sizes, shapes, and features. We'll also cover the different uses for triangles, as well as some of the key considerations to keep in mind while shopping. Whether you're looking for a mathematical instrument, an architectural tool, or something decorative, this guide is sure to give you the information you need to get the perfect triangle for your needs.

Key features

  1. Shape - When purchasing triangles, it is important to consider the shape of the triangle. Is the triangle isosceles, equilateral, or scalene?
  2. Size - The size of the triangle should be of consideration when buying. How long are the sides of the triangle?
  3. Material - It is important to take into account what material the triangle is constructed from. Will the triangle be made of plastic or metal?
  4. Color - Consider what color the triangle will be. Is it a neutral color or a bright color?
  5. Price - What is the cost of the triangle? Are there different prices depending on the size and shape of the triangle?

Important considerations


  • Versatile - Triangles can be used in a variety of applications, both in practical and decorative applications.
  • Strong Structural Support - Triangles are the strongest shape because their sides and angles provide more structural strength than other shapes.
  • Compact Design - Triangles take up less space than other shapes, making them ideal for small areas.
  • Stable Shape - Triangles are a stable shape, meaning they won't shift or move easily.
  • Affordable - Triangles are typically more affordable than other shapes of the same size.
  • Easy to Transport - Triangles are light and easy to transport, making them an ideal choice for travelling.


  • Space Requirements: Triangles can take up a great deal of space, so potential buyers should ensure they have enough room available to accommodate them.
  • Cost: Triangles can be expensive and the cost can vary depending on size and material.
  • Maintenance: Triangles require regular cleaning and maintenance, which can be time-consuming.
  • Durability: Triangles are not the most durable shape and can be easily damaged or dented.
  • Difficult to Assemble: Assembling triangles can be difficult and require special tools and expertise.

Common questions

  1. What is the difference between acute, obtuse, and right triangles? Acute triangles have all angles that measure less than 90 degrees, obtuse triangles have one angle that measures more than 90 degrees, and right triangles have one angle that measures exactly 90 degrees.
  2. What is the Pythagorean Theorem? The Pythagorean Theorem states that in a right triangle, the sum of the squares of the two legs (the sides that meet at the right angle) is equal to the square of the hypotenuse (the side across from the right angle).
  3. What are the different types of triangles? There are several types of triangles, including equilateral, isosceles, scalene, acute, obtuse, and right triangles.
  4. What is the sum of the interior angles of a triangle? The sum of the interior angles of a triangle is always equal to 180 degrees.
  5. What is the relationship between the sides and angles of a triangle? The sides of a triangle are related to the angles by the different trigonometric functions (sine, cosine, and tangent).
  6. What is the formula for finding the area of a triangle? The formula for finding the area of a triangle is A = 1/2bh, where b is the base of the triangle and h is the height.


An interesting fact about triangles is that the ancient Greeks used them to determine whether something was “impossible” or not. They would draw a triangle and if they were able to draw a line from one corner to another, then it was considered to be “possible”. This is known as the “impossible triangle” and it is still used today in mathematical puzzles. [Source:]
