WebMar 13, 2024 · The 30-60-90 and 45-45-90 triangles are used to help remember trig functions of certain commonly used angles. For a 30-60-90 triangle, draw a right triangle whose other two angles are approximately 30 degrees and 60 degrees. The sides are 1, 2 and the square root of 3. The smallest side (1) is opposite the smallest angle (30 degrees).
