Is a figure a square?
This depends what the figure is referencing.
A figure is only a square if it has four sides, all equal, connected by four angles, all right angles (90°).
True or False. A square s inscribe in another figure if each corner of the square touches he figure?
Angles cannot be converted to square feet. The area of an enclosed plane figure (like a square, circle, oval, rectangle, or pentagon) is measured in square feet (or square inches or square cm or square meters). An angle is not an enclosed plane figure, but two straight intersecting lines, and is measured in degrees.
