Triangles: 3 sided polygons Created by G. Antidormi 2005

Can be classified in two ways: Created by G. Antidormi 2005

Can be classified in two ways: by angles Created by G. Antidormi 2005

Can be classified in two ways: by angles by sides Created by G. Antidormi 2005

by angles acute obtuse right Created by G. Antidormi 2005

by sides scalene isosceles equilateral (No equal sides) Created by G. Antidormi 2005

So triangles have 2 classifications: Example 1 Right , scalene triangle Created by G. Antidormi 2005

acute , isosceles triangle Example 2 acute , isosceles triangle Created by G. Antidormi 2005
