What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

What are the coordinates of point I' if triangle GHI is reflected across the x-axis and I is at (6, -2)?

Back

(6, 2) because the y-coordinate changes sign.

What is the difference between translation and reflection?

Back

Translation moves a figure without changing its orientation, while reflection flips it over a line.

How do you determine if two figures are similar?

Back

Two figures are similar if their corresponding angles are equal and their corresponding sides are in proportion.
