Q:

What is a two-dimensional shape?

A:

Quick Answer

A two-dimensional shape is a shape that has width and length but no depth. Another term for a two-dimensional shape is a plane shape, because a two-dimensional shape occurs on one plane, a flat surface that extends in every direction.

Two-dimensional shapes take up area but not volume. Geometric two-dimensional shapes have straight or curved edges that require tools, such as a straight edge or compass, to draw properly. These include triangles, squares, rectangles and circles. Organic two-dimensional shapes are formed of irregular lines. The qualities of geometric two-dimensional shapes are studied in the discipline of plane geometry. Although objects are sometimes portrayed by two-dimensional shapes, all real-world objects have some depth and take up volume, making them three-dimensional.

    What is a kite in geometry?

    A:

    A kite is a quadrilateral, a shape with four straight, flat sides, that has two pairs of sides where the two adjacent sides, the ones that meet, are equal in length. The two angles in a kite where the sides with different measurements meet are identical. The other two angles may or may not be identical.

  • Q:

    What is the perimeter of a kite?

    A:

    The perimeter of a kite is the total distance around the outside of its shape, which means the length of all four of its sides added together. Since a kite has two pairs of matching sides, the standard formula is that the perimeter equals "2a" plus "2b."
