Ex 9.1, 3 Find the distance between P (x1, y1) and Q (x2, y2) when: (i) PQ is parallel to the y-axis. Since PQ is parallel to y-axis x1 = x2. Distance PQ = โˆš("(" ๐‘ฅ_2โˆ’๐‘ฅ_1 ")2 " +"(" ๐‘ฆ_2โˆ’๐‘ฆ_1 ")2" ) = โˆš("(" ๐‘ฅ_2โˆ’๐‘ฅ_2 ")2 " +"(" ๐‘ฆ_2โˆ’๐‘ฆ_1 "2" ) = โˆš((๐‘ฆ_2โˆ’๐‘ฆ_1 "2" )+0) = โˆš("(" ๐‘ฆ_2โˆ’๐‘ฆ_1 ")2" ) = ยฑ (๐‘ฆ_2โˆ’๐‘ฆ_1) = |"y2" โˆ’"y1" |
