# Reflect A Polygon Over An Axis On A Coordinate Grid Worksheet

## 7 problems   In 8th Grade 8, students learn how to reflect a polygon over the x-axis or y-axis on the coordinate plane. Teachers can provide “Reflect a polygon over an axis on a coordinate grid worksheet” to help their students to understand reflection over the x-axis or y-axis.

In this worksheet, a polygon is given on a coordinate plane and students are asked to plot the image of that polygon after reflecting it over the x-axis or y-axis.

To solve this worksheet students should have a good understanding of reflection and coordinate plane. If a point is reflecting over the x-axis then the reflection rule is (x,y)→(x,-y), and if a point is reflecting over the y-axis then the reflection rule is (x,y)→(-x,y). For example, if the vertices of a triangle are A(1,2), B(1,5) and C(4,3), and it is reflected over the x-axis, then the vertices of the new triangle are A(1,-2), B(1,-5) and C(4,-3).

To solve this worksheet students should have a good understanding of reflection and coordinate plane. If a point is reflecting over the x-axis then the reflection rule is (x,y)→(x,-y), and if a point is reflecting over the y-axis then t...
