Height of a tree
Based on the geometric principle that the sides of a 45-45-90 triangle are of equal length.
First, provide students with a number of differently sized isosceles right triangles. Have students measure each side to find a pattern. Once students are convinced that the sides are always equal length, then ask students how we might use that knowledge to measure trees.
