💥 Grade 9 Mathematics ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 🍃🍂🍃🍂Unit one  Lesson 2🍂🍃🍂🍃 ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ══════════════ 🌀Special Types of Sets ══════════════ 🔹Equal Sets:   - Two sets A and B are equal if they have exactly the same elements.   - A = B if every element of A is in B and vice versa.   - Example: A = {1, 2, 3}, B = {3, 2, 1}, then A = B. 🔹Equivalent Sets:   - Two sets are equivalent if they have the same number of elements, regardless of what the elements are.   - Example: A = {1, 2, 3}, B = {a, b, c} are equivalent sets. 🔹 Universal Set (U):   - The set that contains all the elements under consideration.   - All other sets are subsets of the universal set. 🔹 Subset (⊆):   - A is a subset of B if every element of A is also in B.   - Notation: A ⊆ B - Proper Subset (⊂):   - A is a proper subset of B if A ⊆ B and A ≠ B.   - Example: If A = {1, 2} and B = {1, 2, 3}, then A ⊂ B. ══════════════ 🍁@SmartstudyStream ◉ 𝐓𝐡𝐞 𝐒𝐭𝐫𝐞𝐚𝐦 𝐭𝐨 𝐒𝐦𝐚𝐫𝐭 𝐑𝐞𝐬𝐮𝐥𝐭𝐬!
