Reflect the shape in the line \(x = -1\). The line \(x = -1\) is a vertical line which passes through -1 on the \(x\)-axis. The line \(y = 1\) is a horizontal line which passes through 1 on the ...

Big Idea – We can describe, measure, and compare spatial relationships. to build on students' knowledge of line symmetry and develop students' reasoning with properties of symmetry to develop an ...

b. Or “The points can cross the line of symmetry”. c. Students will gain an awareness of the property of equidistant. You might hear them say, “The point on one side of the line is the same distance ...

A shape has a line of symmetry when the folded part sits perfectly on top with all edges matching. The number of lines of symmetry in a regular polygon is equal to the number of sides. A shape has ...
