After watching a clip from "The Wizard of Oz", we realized that the Scarecrow knew a little bit about math. We then talked about one of the words he said (isosceles) and how it related to geometry.
Triangles can be sorted into groups based on two different factors: length of side and size of angle. If we look at the angles of a triangle, they always sum to 180 degrees. When using angle size, triangles can be labeled as acute, obtuse or right. When looking at the length of the sides of a triangle, triangles can be labeled as equilateral, isosceles, or scalene.
