Today I will be helping you with defining the angles of a triangle.When looking at a triangle, it can either be Right, Obtuse, or Acute.
A right triangle means there is one 90 degree angle in the triangle, that would look like this.
The square in the bottom left corner means that angle is exactly 90 degrees, which is what makes it a right triangle. A super simple way to be able to tell if it is a right triangle or not is to see if it has an "L" or not. If there is a perfect "L", then it is not right. A great visual tool to be able to tell this is if you stick one arm straight up in the air, and the other arm straight to the side.
An obtuse triangles is one that has an angle that is larger than 90 degrees. If there is even a single angle that is larger than 90 degrees, the triangle is automatically obtuse. This is what an obtuse triangle looks like.
An acute triangle is the opposite. It is when all of the angles are less than 90 degrees. That looks like this.
If you were to stick your arms out to make a right triangle, this shape would be smaller than that. That is a really simple way to identify an acute triangle.
