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.
A. 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?
B. Kyla’s scale factor is incorrect. It should be One-half for the ratio StartFraction Original over scaled figure EndFraction.
C. Kyla used the wrong corresponding sides.
D. Kyla multiplied the corresponding sides by 2 instead of dividing to find the original.
E. Kyla added 2 to the corresponding sides instead of subtracting.
