Question

What is the differences and similarities between 45 45 90 triangles and 30 60 90 triangles? I have to create a venn diagram comparing the two.

Answer 1

Uhh, here are a few that I remember off the top of my head:

- The 45-45-90 triangle is also isosceles, due to the two 45-degree angles it has. However, the 30-60-90 triangle is scalene.

- The 45-45-90 triangle is half of a square (to see this, stick two copies of it together at their hypotenuses), while the 30-60-90 triangle is half of an equilateral triangle (join two copies at their longer leg).
