Question 2
If a scale factor of 2 is applied to figure A, which of these would be a corresponding side length on the new triangle?
Responses
A 4 ft4 ft
B 12 ft12 ft
C 18 ft18 ft
D 24 ft

Answer 1

I can’t see figure A or B in your message. Please either upload the images or tell me at least one pair of corresponding side lengths (one from A and the matching one from B).

How to solve each question once you have the lengths:
- Question 1 (scale factor from A → B): k = (length in B) ÷ (corresponding length in A). Pick the option that equals that quotient.
- Question 2 (scale factor 2 applied to A): multiply any side length of A by 2. For the given answer choices:
- If A had a side 2 ft → scaled = 4 ft (choice A)
- If A had a side 6 ft → scaled = 12 ft (choice B)
- If A had a side 9 ft → scaled = 18 ft (choice C)
- If A had a side 12 ft → scaled = 24 ft (choice D)

Send the figures or the original side lengths and I’ll pick the correct options.
