Question

Explain how you determine the type of triangle given the sides: 4, 10, 11.

Answer 1

So we have a few different types of triangle, namely

Equilateral
Isosceles
Scalene

Equilateral triangles have three equal sides and so they have 3 equal angles of 60 degrees

Isosceles triangles have 2 equal sides and two equal angles opposite them

Scalene triangles have NO equal sides and so three different angles

So as an example:

Answer 2

So what do you think about the triangle given by 4, 10 and 11?

Is it an isosceles, scalene, or equilateral triangle?

Answer 3

We can also classify triangles based on their angles so this might be helpful too
