Geometric figures are shapes that can be described using mathematical equations. Ellipsoids, which have 10 letters, are three-dimensional shapes with curved surfaces that are symmetrical about each of the three axes. Areas, which have 5 letters, are two-dimensional shapes that can be measured in square units. ELLIPSES, which have 8 letters, are two-dimensional shapes with curved surfaces that are symmetrical about two axes. Cones, which have 5 letters, are three-dimensional shapes with a circular base and a curved surface that tapers to a point. Rhombi, which have 6 letters, are two-dimensional shapes with four equal sides and opposite angles that are equal.
