Understanding Scaled Copies
A scaled copy happens when every length in the original figure gets multiplied by the same number. Think of it like zooming in or out on a photo while keeping everything proportional.
When looking at scaled copies, pay attention to corresponding parts - these are matching parts between the original figure and the copy. For example, Triangle DEF is a scaled copy of Triangle ABC because each side length in ABC was multiplied by 1.5 to get DEF's sides.
Corresponding angles are angles in the same positions on scaled copies. Even though the size changes, these angles stay the same! In our triangle example, Angle C and Angle F are corresponding angles.
Quick Tip: When examining scaled copies, always check that ALL measurements have been multiplied by the exact same scale factor. If even one measurement doesn't follow the pattern, it's not a true scaled copy.
