Skateboards, mountain climbing, billiards… Don't you just love this stuff? That's why NUMBEROCK put it all into this song about types of triangles that is filled with real-world connections. Triangles are all around us, so it is easy to make this song especially relevant to the lives of students. Learn how to classify types of triangles by their sides (scalene, isosceles, & equilateral) and by the angles (acute, obtuse, & right) in this ridiculously catchy rock song.

Video aligns with the following Common Core State Standards

4.G.A.2 ✦ 4.G.2
Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.

Video aligns with the following Math TEKS standards
