Ordering Sides and Angles of a Triangle Worksheets

Visualize a triangle. You know the measures of all three angles, but not the side lengths. Can you point out its longest side? Now, what if you are given the side lengths and no angle measure? Can you determine the largest angle? Both are as easy as pie, if you know the relationship between the side lengths and angles of a triangle. There’s no big deal remembering it: the largest angle of the triangle is opposite to its longest side and the smallest angle is opposite to the shortest side. Direct high school students to implement this fact and order the sides and angles of triangles in this ensemble of printable worksheets. Sample our free worksheet and get started!
