45-45-90 And 30-60-90 Triangles Worksheets
Updated on June 7, 2023
Students who study our 45-45-90 and 30-60-90 triangles worksheets will learn about special right triangles and be able to solve related problems.
What is 45-45-90 triangle?
A 45-45-90 triangle is a right triangle with angles that are 45 degrees, 45 degrees, and 90 degrees. The ratio of the sides in a 45-45-90 triangle is always 1:1:sqrt(2). This means that if the length of one side of the triangle is “x,” then the length of the other two sides will also be “x.”
What is 30-60-90 triangle?
Meanwhile, a 30-60-90 triangle is a right triangle with angles that are 30 degrees, 60 degrees, and 90 degrees. The ratio of the sides in a 30-60-90 triangle is always 1:sqrt(3):2. This means that if the length of the shorter leg (the side that is opposite the 30 degree angle) is “x,” then the length of the longer leg (the side that is opposite the 90 degree angle) is “x*sqrt(3)” and the hypotenuse is “2x”.
