Practice Questions
Test your understanding with targeted questions
What is the scale factor if triangle ABC is reduced to half its size?
💡 Hint: Remember, a scale factor less than 1 indicates reduction.
If the original triangle has vertices (2, 3), what would the new coordinates be when reduced by scale factor 1/2?
💡 Hint: Multiply each coordinate by 1/2.
