Which Venn diagram correctly represents the relationship: "All squares are rectangles, but not all rectangles are squares"?

📌 Step 1: Understand the statement
"All squares are rectangles" → squares are a SUBSET of rectangles
"Not all rectangles are squares" → rectangles is the LARGER set

📌 Step 2: Match to Venn diagrams
A: Squares inside Rectangles ✓ (correct subset relationship)
B: Overlapping circles → implies some squares are not rectangles ✗
C: Rectangles inside Squares → backwards ✗

📌 Answer: A

💡 Tip: "All A are B" always means A is completely inside B in a Venn diagram.
