I have combined the "Monster Puzzles" over 45-45-90 and 30-60-90 triangles into one product to offer as a discounted bundle. These two puzzles are awesome! They involve a collage of triangular figures where the triangles are strictly 45-45-90, 30-60-90 degree triangles. Students are given only one dimension on the figure. From there, they must calculate the remaining dimensions using their knowledge about these triangles. The second figure includes a circle with the 45-45-90 triangles. This is a great activity to guide students along in mastering the ratios of the sides of these very special triangles. Students have a challenging time with these unusual puzzles, while at the same time, they find the puzzles to be a great deal of fun!
