Get Practice Reflecting Points In The Coordinate Plane

A reflection point occurs when a figure is constructed around a single point known as the point of reflection or centre of the figure. For every point in the figure, another point is found directly opposite to it on the other side.

Reflection Rules ReflectionReflection RuleIn Words Over the x-axis (x,y)-->(x,-y) Negate the y coordinates Over the y-axis (x,y)-->(-x,y) Negate the x coordinates Over y=x (x,y)-->(y,x) Swap the x and y coordinates Origin (x,y)-->(-x,-y) Negate both the x and y coordinates

Reflection is a type of transformation that flips a shape in a mirror line (also called a line of reflection) so that each point is the same distance from the mirror line as its reflected point. E.g. Triangle P has been reflected in the line x = 4 x=4 x=4 to give Triangle Q.

In order to reflect a graph about the origin, the rule of translation for each point is (a,b) reflects to (-a,-b). The reflection of the point (a,b) across the line y = x is (b,a). By following these rules, you can reflect any line or figure across any of the three most common lines of reflection or the origin.

(i) The image of P(3,-5) when reflected in X-axis will be (3,5). When you reflect a point across the X-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). Image of P(3,-5) when reflected in Y axis will be (-3,-5).

When a point is reflected across the X-axis, the x-coordinates remain the same. But the Y-coordinates are transformed into their opposite signs. Therefore, the reflection of the point (x, y) across X-axis is (x, -y).

Now, the most efficient way to find the image of this point is to apply one of the properties of rotation about the origin: this one in particular, that a rotation of 90 degrees counterclockwise about the origin is equivalent to the coordinate transformation that the coordinates 𝑥, 𝑦 map to the coordinates negative 𝑦, ...

A point is considered to be a reflection of another point when the absolute values of the coordinates are the same but the signs of one of the values are opposites.

When a point is reflected along the y axis, the X coordinate becomes the opposite number and the y coordinate stays the same. Likewise, when a point is reflected along the X axis, the X coordinate stays the same and the y coordinate becomes the opposite. The x coordinate is opposite.
