This is an introductory of the 45-45-90 and 30-60-90 special right triangles theorems. Students will follow the directions on the worksheet to discover the ratio between sides on a 45-45-90 triangle starting with a square with side “x” and then repeat that for a 30-60-90 triangle given an equilateral triangle with side “2x.” Remind them that they are not measuring the sides of the square of with a ruler. They are keeping all segments in terms of “x”.
