The scale factor can be obtained by dividing the length of a side in the second shape by the length of the corresponding side. The scale factor is a fraction or decimal number that can be used to scale up or down a shape.
Know MoreA scaled up or scaled down shape is identical to the original shape in terms of number of sides and size of internal angles. The original and scaled shape can be matched up based on the equivalent angles. The scale factor is calculated dividing a side on the resulting shape by the matching side on the original. The lengths of other sides on the scaled shape can be calculated by multiplying other sides of the original by the scale factor.

Full Answer >To find the perimeter of a trapezoid, add up the length of each of the sides of the shape. Use the equation P = a + b + c + d.
Full Answer >The lengths of the sides of a 30-60-90 triangle always exist in the proportional pattern 1:2:sqrt 3. The shorter side is half as long as the hypotenuse, and the length of the longer side is found by multiplying the length of the shorter side by the square root of three. Knowing this pattern makes it possible to find the lengths of the other two sides if one side is given.
Full Answer >A kite, which is a quadrilateral with two different pairs of adjacent sides that are equal in length, has only one line of symmetry. A line of symmetry for any polygon can be found by reflecting the polygon over a line so that the polygon or figure is divided into two halves that are mirror-images. In a kite, this line of symmetry is down its center.
