IXL - Reflections: graph the image (Geometry practice)

Graph the image of square

after a reflection over the

-axis.

Coordinate plane graph with 4 quadrants, x-axis coordinates from -10 to 10, y-axis coordinates from -10 to 10. The following data are shown. Point (-10, -10). Point (-4, -10). Point (-4, -4). Point (-10, -4).

question

Graph the image of

△

after a reflection over the

-axis.

key idea

A reflection flips a figure over a line to create a mirror image.

When a point is reflected over the

-axis,

the

-coordinate

changes sign.

solution

Reflect point

(

–

)

over the

-axis.

Since

is 4 units to the left of the

-axis,

is 4 units to the right of the

-axis.

Now reflect point

(

–

)

over the

-axis.

Since

is 4 units to the left of the

-axis,

is 4 units to the right of the

-axis.

Now reflect point

(

–

)

over the

-axis.

The reflected points form a triangle congruent to
