Under the reflection about the line y = -x, P( x,y ) = P'( -y,-x ) P( 3,-2 ) = P'( 2,-3 ) Hence, P'( a,b ) = P'( 2,-3 ) Equating both components, we get, a = 2 , b = -3 Again, Under the reflection about the line x = h, P( x,y .....
Under reflection in the line y = x, P( x,y ) = P'( y,x ) A( 7,4 ) = A'( 4,7 ) Again, Under the reflection in the line y = b, P( x,y ) = P'( x,2b - y ) A( 4,7 ) = A'( 4,1 ) For the value of b, 2b - y = 1 2b - 7 = 1 2b = 1 + 7 2b = .....
