The scale factor from the solid triangle to the dashed triangle is 0.2.
Dilation involves changing the size of a shape.
How does dilation works?
Dilation of a figure will leave its sides get scaled (multiplied) by same number. That number is called the scale factor of that dilation.
Its also called scaling of a figure, but due the involvement of coordinates, it involves a center of a dilation, which is like a pinned point which stays at same place after dilation.
Its like we enlarge or shorten the size of the figure (or keep it same, when scale factor = 1).
In order to calculate the dilation from the solid triangle to the dashed triangle, we calculate the length of corresponding sides of both triangles.
The measure of the corresponding sides at:
Solid = 15
Dashed = 3
The scale factor (k) is then calculated as:
k = Dashed /Solid
This gives
k = 3/15
Divide;
k= 0.2
Hence, the scale factor from the solid triangle to the dashed triangle is 0.2.
