Quickly review how to reflect an object across the y-axis. This video provides a simple rule for reflection across the y-axis. • To reflect a triangle across the y-axis, you simply need to change the sign of the x-coordinate of each point while keeping the y-coordinate unchanged. Here are the steps required to reflect the triangle with points A(-6,2), B(-2,2), and C(-2,8) across the y-axis: • 1. Identify the Original Triangle: Start by identifying the vertices of the original triangle on the coordinate plane. In this case, the vertices are A(-6,2), B(-2,2), and C(-2,8). • 2. Reflect Each Point Across the Y-Axis: To reflect each point across the y-axis, simply change the sign of the x-coordinate while keeping the y-coordinate unchanged. • - For point A(-6,2), the reflected point will be A'(6,2). • - For point B(-2,2), the reflected point will be B'(2,2). • - For point C(-2,8), the reflected point will be C'(2,8). • 3. Plot the Reflected Triangle: Plot the reflected points A'(6,2), B'(2,2), and C'(2,8) on the coordinate plane. Connect these points to form the reflected triangle. • 4. Verify: Check that the reflected triangle appears symmetrical with respect to the y-axis. The distances between corresponding vertices of the original and reflected triangles should be the same, and the orientation of the triangle should be opposite. • Following these steps, you can accurately reflect the given triangle across the y-axis on the coordinate plane. • #transformations #coordinategeometry #maths
