Bridge Design and Building

Types of Triangles - Medium

 

In year 7 and 8 you learned that a truss involves some

combination of triangles.

 

Triangles may be classified by their sides:

 

 

equilateral - all side lengths are equal

 

 

 

 

 

 

 

scalene - no side lengths are equal

 

 

 

 

 

 

isoceles - 2 side lengths are equal

 

 

 

 

 

 

 

 

 

And triangles may be classified by their angles:

 

acute (all angles are acute)

 

 

 

 

 

 

 

 

right (one angle is right)

 

 

 

 

 

 

 

obtuse (one angle is abtuse)

 

 

 

 

 

 

 

 

 

equiangular (all angles are equal)

 

 

 

 

 

 

 

 

 

Task 1

After becoming familar with the ways in which triangles can be described, classify the triangles in the worksheet.
