There are many types of triangles that you will come across in math. In this post we are going to look at the 6 most common triangles you will see in math questions.
Let's start with the basics
These two rules are true for ANY type of triangle. Keep this in mind as we go through the different types.
The little square in the corner means the angle equals 90°
This is where all corners of triangles are acute angles (smaller than 90°)
This triangle has one corner that contains a obtuse angle (larger than 90°)
When all sides and angles are the same and all of them equal 60°
Two of the sides and two of the angles are the same.
No sides or angles are equal to one another.
You will use these triangles in math all throughout high school so make sure you are familiar with all the different triangles!
