Which of the following statements is not always true?
A. Two circles are similar
B. Two isosceles right triangles are similar
C. Two rectangles are similar
D. Two equilateral triangles are similar
✅ Answer & Solution
✅ Correct Answer: C
Two rectangles need not have equal ratios of corresponding sides, so they are not always similar (e.g. a 2x4 rectangle and a 2x6 rectangle are not similar). All circles, isosceles right triangles, and equilateral triangles are always similar to each other respectively.
