Types of Triangles!

By the TRIO of  Kate, Gal, and Jaxon          


    

 A polygon with three sides is called a triangle. 

We learned there  are five kinds of triangles. 

  ∆     ∆     ∆     ∆    ∆

The first one is an equilateral triangle. 

It has 3 equal sides and 3 equal angles. 



 



When you rotate an equilateral triangle,  it looks the same. 

  ∆     ∆     ∆     ∆    ∆

 Secondly, is the isosceles triangle. Gal was surprised to know that her necklace had an isosceles triangle on it!

The isosceles triangle has 2 equal sides and 2 equal angles.

  ∆     ∆     ∆     ∆    ∆

 Thirdly, is the isosceles right. 

An isosceles right has 2 equal sides and  2 equal angles. 

However,  it has 1 right angle.   

  ∆     ∆     ∆     ∆    ∆

 Next, is the scalene. 

 

It has no equal sides or angles.

  

∆     ∆     ∆     ∆    ∆

 In addition, there is the scalene right. 

 

The scalene right has no equal sides, but it has 1 right angle. 

  ∆     ∆     ∆     ∆    ∆

These are the five different triangles.


Ms. Palmer, Jaxon's mom, wanted to know what kind of a triangle the trio would make. Here is the human isosceles triangle!

 

  

Also, here is the equilateral necklace Mrs. Yollis' husband made for her!

What is your favorite triangle and why?

Are there any triangles at your school or house?
