Symmetry transformations Grade 10 Math quiz

📚 Quick Study Guide

• 📐 Translation: A transformation that slides a figure along a straight line. Every point of the figure moves the same distance in the same direction.
• 🔄 Rotation: A transformation that turns a figure about a fixed point (the center of rotation). Defined by the angle of rotation and the direction (clockwise or counterclockwise).
• зеркало Reflection: A transformation that flips a figure over a line (the line of reflection). The reflected image is a mirror image of the original.
• 📈 Dilation: A transformation that enlarges or reduces a figure by a scale factor with respect to a center point. If the scale factor is greater than 1, the figure is enlarged; if it's between 0 and 1, the figure is reduced.
• ➕ Combining Transformations: Complex transformations can be achieved by combining two or more basic transformations. The order of transformations matters!
