Find the dimensions of the original triangle. A scale factor multiplies the length of each side of the shape that is enlarged. When two objects are given to be mathematically similar then the length, area and volume scale factors are related as follows:
Determine The Sign Of The Enlargement Factor/ Scale Factor.
The ratio is called scale factor of enlargement. Locate the centre of enlargement, then draw ray lines from the centre of enlargement through the vertices of the shape. A triangle was increased by a scale factor of 2 resulting in the new dimensions as 6 units by 10 units by 12 units.
Enlarge The Shaded Shape By Scale Factor 2 2 About The Point (1,2) (1,2) Plot The Centre Of Enlargement On The Coordinate Grid.
An enlargement is the only transformation that changes the size of a shape. Then draw ray lines from the centre of enlargement through the vertices of the original shape. The scale factor of 2 represents that you will get a new shape that will be twice the size of the actual figure.
Scale Factor = 3/6 (Divide Each Side By 6).
Rays are often drawn in the wrong direction, i.e., from the centre through the object, which leads to an incorrect enlargement. What scale factor makes a figure smaller? The base in the original shape is 1 1, so the base in the enlarged shape will be 2 2.
Enlarge The Triangle Abc By Scale Factor 2 2 About The Point O.
