Answer 1

Question:

Consider the enlargement of the triangle.

A triangle has side lengths of 7 millimeters, B, and A. A larger triangle has side lengths 14 millimeters, 7 millimeters, 16 millimeters.

Kyla calculated the scale factor of the enlargement as 2. She then determined that A = 32 mm and B = 14 mm. What was Kyla’s error?

Kyla’s scale factor is incorrect. It should be One-half for the ratio StartFraction Original over scaled figure EndFraction.

Kyla used the wrong corresponding sides.

Kyla multiplied the corresponding sides by 2 instead of dividing to find the original.

Kyla added 2 to the corresponding sides instead of subtracting.

Answer:

C.) Kyla multiplied the corresponding sides by 2 instead of dividing to find the original.

Step-by-step explanation:

Answer 2

Kyla's error was: C. Multiplying the corresponding sides by the scale factor of 2 instead of dividing to find the original.

What is a Scale Factor of a Dilation?

Scale factor of a dilation = dimension of the image (new figure) / corresponding dimension of the preimage (original figure)

If the dilation is an enlargement, the scale factor will be a whole number. If it is a reduction, the scale factor would be a fraction.

Since the scale factorof the enlargement is 2, then, to get A and B, Kyla should have divided the corresponding sides to A and B by 2 instead of multiplying by 2.
