To reflect the rectangle MNOP across the given lines of reflection, we need to find the coordinates of the reflected points.1) Reflection across the line
:The line
is the y-axis. To reflect a point across the y-axis, we change the sign of the x-coordinate while keeping the y-coordinate the same.So, the reflected points are:
2) Reflection across the line
:The line
is a horizontal line. To reflect a point across a horizontal line, we change the y-coordinate to
, where
is the y-coordinate of the line of reflection.So, the reflected points are:
3) Reflection across the line
:The line
is a diagonal line. To reflect a point across the line=x
M(-2,6) \rightarrow M'(6,-2)
N(2,8) \rightarrow N'(8,2)
O(5,2) \rightarrow O'(2,5)
P(1,0) \rightarrow P'(0,1)
y=-x
y=-x
y=-x
M(-2,6) \rightarrow M'(-6,2)
N(2,8) \rightarrow N'(-2
Therefore, the reflected rectangle MNOP across the given lines of reflection are:1)
2)
3)
4)
