Q:

What shape has four sides and three corners?

A:

There is no shape that has four sides and three corners. Two-dimensional shapes, known as polygons, have an equal number of sides and angles. In addition, none of the common three-dimensional shapes have four sides and three corners.

Full Answer

A polygon with three corners is a triangle, which also has three sides. Four-sided polygons are known as quadrilaterals. Examples of quadrilaterals include the square, rectangle and parallelogram. Common three-dimensional shapes include the cube, triangular prism, cone, cylinder and tetrahedron. None of the shapes have three corners, or vertices. Some, such as the cylinder, have no corners. Others, such as the tetrahedron, have four vertices.

  • Q:

    What is a list of some polygons?

    A:

    A polygon is identified based on the number of its sides and vertices. Polygons are made of straight lines, called edges or sides, that meet in corners to form a closed circuit. The least number of sides needed to form a closed loop is three. A three-sided polygon is called a triangle. The list of common polygons includes quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon and decagon.

  • Q:

    How do you solve for the perimeter of an isosceles triangle?

    A:

    The perimeter of a triangle is the sum of all the sides of the triangle, and you determine the perimeter of any triangle by adding the lengths of all three sides. Since an isosceles triangle has two sides of equal length, start by multiplying the length of one of the equal sides by two. Then, add the product to the length of the base side. The resulting sum is the perimeter of the triangle. Using either a pen and paper or a calculator, you can make these simple calculations in just a few minutes.

  • Q:

    Why is the triangle the strongest shape?

    A:

    The triangle is the strongest shape due to the rigidity of its sides, which allows them to transfer force more evenly through their sides than other shapes. Triangles are used extensively in the construction of buildings and bridges.
