rhombus : a simple quadrilateral whose four sides all have the same length.
square : a plane figure with four equal straight sides and four right angles.
trapezoid : a quadrilateral with only one pair of parallel sides.
cube : a symmetrical three-dimensional shape, either solid or hollow, contained by six equal squares.
triangle : a polygon with three corners or vertices and three sides or edges which are line segments.
pentagon : a plane figure with five straight sides and five angles.
pyramid : a monumental structure with a square or triangular base and sloping sides that meet in a point at the top.
parallelogram : four-sided plane rectilinear figure with opposite sides parallel.
hexagon : a plane figure with six straight sides and angles.
cone : a solid or hollow object that tapers from a circular or roughly circular base to a point.
prism : a solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
plane : a flat, two-dimensional surface.
octagon : a plane figure with eight straight sides and eight angles.
right angle : an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.
cylinder : a solid geometric figure with straight parallel sides and a circular or oval section.
skew lines : two lines that do not intersect and are not parallel.
semicircle : a half of a circle or of its circumference.
circle : the set of all points in a plane that are at a given distance from a given point, the centre.
acute angle : an angle smaller than a right angle (less than 90°).
