Question 5 of 5
A scale drawing
A scale drawing
A scale drawing of an object is the same shape at the object but a different size. The scale of a drawing is a comparison of the length used on a drawing to the length it represents. The scale is written as a ratio. The ratio of two corresponding sides in similar figures is called the scale factor
Scale factor = length in image / corresponding length in object If one shape can become another using revising, then the shapes are similar. Hence, two shapes are similar when one can become the other after a resize, flip, slide or turn. In the photograph below showing the side view of a train engine. Scale factor is 1:200
This means that a length of 1 cm on the photograph above corresponds to a length of 200 cm or 2 m , of the actual engine. The scale can also be written as the ratio of two lengths.
What will affect the similarity of any two polygons?
Select one option. Answers are shown after the test.
