What are the reflection points for a triangle over the x-axis?

• The reflection points are the midpoints of the sides of the triangle

• The reflection points are the three midpoints of the triangle

• The reflection points for a triangle over the x-axis are the three vertices of the original triangle with the y-coordinates negated.

• The reflection points are the three points where the triangle intersects the x-axis

Draw the line of symmetry for the given polygon.

• The line of symmetry is drawn by connecting the vertices of the polygon

• The line of symmetry for the given polygon can be drawn by connecting the midpoints of each side to the opposite vertex.

Explain how to identify if a figure has been reflected correctly over a line of symmetry.

• Count the number of vertices in the figure

• Check if the pre-image and image are mirror images of each other across the line of symmetry.

• Check if the figure has been translated horizontally

• Verify if the figure has been rotated instead of reflected
