Reflection

A point P (a, b) is reflected in the x-axis to P’ (2, -3). Write down the values of a and b. P” is the image of P, reflected in the y-axis. Write down the co-ordinates of P”. Find the co-ordinates of P”’, when P is reflected in the line, parallel to y-axis, such that x = 4.

A point \[P\text{ }\left( a,\text{ }b \right)\] is reflected in the \[x-hub\] to \[P'\text{ }\left( 2,\text{ }-\text{ }3 \right).\] We realize that, \[{{M}_{x}}~\left( x,\text{ }y \right)\text{...

The point (-2, 0) on reflection in a line is mapped to (2, 0) and the point (5, -6) on reflection in the same line is mapped to (-5, -6). (i) State the name of the mirror line and write its equation. (ii) State the co-ordinates of the image of (-8, -5) in the mirror line.

(I) We realize that, impression of a point \[\left( x,\text{ }y \right)\]in \[y-hub\] is \[\left( -\text{ }x,\text{ }y \right).\] Thus, the point \[\left( -\text{ }2,\text{ }0 \right)\] when...

Points (3, 0) and (-1, 0) are invariant points under reflection in the line L1; points (0, -3) and (0, 1) are invariant points on reflection in line L2. (i)Write down the images of P and Q on reflection in L2. Name the images as P” and Q” respectively. (ii) State or describe a single transformation that maps P’ onto P”.

(i) \[P\text{ }=\text{ }Image\text{ }of\text{ }P\text{ }\left( 3,\text{ }4 \right)\text{ }in\text{ }{{L}_{2}}~=\text{ }\left( -3,\text{ }4 \right)\] Also, \[Q\text{ }=\text{ }Image\text{ }of\text{...

Points (3, 0) and (-1, 0) are invariant points under reflection in the line L1; points (0, -3) and (0, 1) are invariant points on reflection in line L2. (i) Name or write equations for the lines L1 and L2. (ii) Write down the images of the points P (3, 4) and Q (-5, -2) on reflection in line L1. Name the images as P’ and Q’ respectively.

(I) We realize that, each point in a line is invariant under the appearance in a similar line. As the focuses \[\left( 3,\text{ }0 \right)\]and \[\left( -\text{ }1,\text{ }0 \right)\]lie on the...
