The crossword solution for the term 'It's Measured in Both Feet and Meters' is POEM, which stands for 'Perpendicular, Oblique, Equilateral, and Mutually-Included'. This is a type of measurement used in geometry, where the angles of a triangle are measured in degrees. The four types of angles are perpendicular, oblique, equilateral, and mutually-included. Perpendicular angles are two angles that form a right angle, oblique angles are two angles that do not form a right angle, equilateral angles are three angles that are all equal, and mutually-included angles are two angles that share a common side. All of these angles can be measured in both feet and meters.
