Triangles and their Types

Preview

I bet you knew about from when you were in Kindergarten but did you ever come to realize that there are actually different types of triangles and each have a name.These are the triangles and their descriptions:

Equilateral Triangle-All three sides are equal.

Isosceles Triangle-Two sides are the same length, but one side is different.

Scalene Triangle-All sides are different.

Right Triangle-One angle is a right angle.

Acute Triangle-One angle is an acute angle.
 

 Obtuse Triangle-One angle is an obtuse angle.

These are all the six types of angles and the first three triangles are determined by the length of their sides and the other three are determined by the measurements of their angles.
So now you know that there are different types of triangles so the next time you spot one try and figure out which one it is.
Now try some of these and make sure to watch the video on YouTube.
