Randy draws these two triangles with links given in the centimeters which scale factor does she use to create this copy on the right from the original on the left 10” x 15” x 18”

Answer 1

To find the scale factor used to create the copy on the right from the original on the left, we need to compare the corresponding side lengths of the two triangles.

Let's label the original triangle as triangle A and the copy as triangle B.

The original triangle A has side lengths of 10", 15", and 18".

Now, to find the corresponding side lengths of triangle B, we need to determine the scaling factor.

Let's consider the longest side of triangle A, which is 18".

For triangle B to be an identical scaled copy, the corresponding side should also be 18".

Now, let's compare the second longest side of triangle A, which is 15", with the corresponding side of triangle B.

We can see that the corresponding side of triangle B is also 15".

Finally, let's compare the smallest side of triangle A, which is 10", with the corresponding side of triangle B.

We can see that the corresponding side of triangle B is also 10".

Since all corresponding side lengths of triangle A and triangle B are equal, the scale factor is 1.
