A smartboard lesson that reviews angles and discusses the ways we classify triangles (by their sides and angles). It has built-in partner discussion and hints to aid discussion. It discusses acute, obtuse, right, scalene, isosceles, and equilateral triangles.
The last slide refers to a triangle sort (available on the VA Dept. of Education website) and a challenge worksheet (available for free at my store!)
