SCALE FACTOR AND SIMILARITY SCALE FACTOR
A scale drawing of an object is of the same shape as the object but of a different size.
The scale of a drawing is a comparison of the length used on a drawing to the length it represents. The value of scale is written as a ratio.
The ratio of two corresponding sides in similar figures is called the scale factor.
If one shape can become another using Resizing then the shapes are Similar.
Hence, two shapes are Similar when one can become the other after a resize, flip, slide or turn.
Below you see a student's mathematical model of a farmhouse roof with measurements. The attic floor, ABCD in the model, is a square. The beams that support the roof are the edge of a rectangular prism, EFGHKLMN.
E is the middle of AT, F is the middle of BT, G is the middle of CT, and H is the middle of DT. All the edges of the pyramid in the model have length of 12 m.
What is the length of EF, where EF is one of the horizontal edges of the block ?
