Geometry

(geometry) any flat shape with four straight sides, the opposite sides of which are equal and parallel to each other

(geometry) a polyhedron with four flat sides, a triangular pyramid

a geometric figure with eight triangular faces, twelve edges, and six vertices

The faces of an octahedron are all equilateral triangles, and each vertex is the meeting point of four triangles.

a three-dimensional figure with twelve regular pentagonal faces, thirty edges, and twenty vertices

The dodecahedron is a Platonic solid, meaning it has identical faces, edges, and angles.

a three-dimensional figure with twenty equilateral triangle faces, thirty edges, and twelve vertices

The icosahedron is a Platonic solid, exhibiting symmetry and regularity in its faces, edges, and angles.

the state or quality of being curved or bent, describing the shape or contour of an object or surface

The curvature of the race track posed a challenge for drivers navigating tight turns.

(geometry) a symmetrical open curve that is similar to the path of an object thrown into the air passes till it falls back to earth

The path of a thrown ball forms a parabola.

a geometric curve formed by the intersection of a plane with two cones, resulting in two symmetrical branches

The hyperbola is a conic section formed by intersecting a plane with two cones on opposite sides of the plane.

a solid shape resembling a donut or ring, made by spinning a circle around a line that does not cut through the circle

The handle of a coffee mug is shaped like a torus, providing a comfortable grip.

the section of a solid shape that remains after a parallel cut, featuring a flat top and a bottom that is larger or smaller than the top

a curved shape with narrow points at the ends that appears wider in the middle, like the shape of the moon in its first and last quarters

The moon hung low in the sky, its slender crescent casting a gentle light.

a surface in three-dimensional space formed by moving a straight line along a helix

(Fungi) a remnant of the partial veil that in mature mushrooms surrounds the stem like a collar

(geometry) a flat shape with four equal sides in which opposite angles are equal

a straight line that a curve approaches indefinitely but never intersects, characterizing the limiting behavior of the curve

The hyperbola has asymptotes that represent the lines the curve approaches but never crosses.

(geometry) a flat shape with four flat sides, two of which are parallel

a structure made of strips of wood, metal, or other rigid material arranged in a criss-crossed, grid-like pattern

She decorated the side of her garden shed with a lattice pattern made of interwoven twigs.

a rectangular figure that has unequal adjacent sides with arched angles

The rug in the living room was an attractive oblong with intricate patterns.

(geometry) a four-sided figure with opposite equal angles, forming a diamond shape

The pattern on the floor was made of blue and white lozenges.

a polygon with twenty sides and twenty angles
