Mathematics
Special Right Triangles: 45-45-90 and 30-60-90
Students use the side-ratio patterns of 45-45-90 and 30-60-90 triangles to find missing sides, including square diagonals and equilateral-triangle heights.
Mathematics
The Pythagorean Theorem and Its Converse
Students find missing sides of right triangles in real-world situations and use the converse to test whether side lengths make a right triangle.
