Ex 10.1, 3 Find the distance between P (x1, y1) and Q (x2, y2) when: (ii) PQ is parallel to the x-axis. Since PQ is parallel to x-axis y1 = y2. Distance PQ = โ("(" ๐ฅ_2โ๐ฅ_1 "2" +"(" ๐ฆ_2โ๐ฆ_1 ")2" ) = โ("(" ๐ฅ_2โ๐ฅ_1 ")2 " +"(" ๐ฆ_1โ๐ฆ_1 ")2" ) = โ("(" ๐ฅ_2โ๐ฅ_1 ")2" +0) = โ("(" ๐ฅ_2โ๐ฅ_1 ")2" ) = ยฑ (๐ฅ_2โ๐ฅ_1) = |๐_๐โ๐_๐ |
