Answer:
<em>4 </em>
Step-by-step explanation:
The solid triangle dilated to become the dashed triangle.
Compare two corresponding sides. For example, the vertical side of the solid triangle measures 3 units. The vertical side of the dashed triangle measures 12 units. 12/3 = 4. The dilation is 4. The scale factor is 4.
Answer:
Scale factor: 4
Step-by-step explanation:
Let m be scale factor.
We have been given two triangles such that dashed triangle is image of the pre-image solid triangle.
First of all, we will find length of bases of both triangles by counting the units.
Base of pre-image: 2 units.
Base of image: units.
We know that after multiplying a side of pre-image by scale factor, we get image.
Therefore, the scale factor for given diagram is 4.
