Challenge Problems
Push your limits with advanced challenges
Enlarge a triangle with vertices P(2, 3), Q(4, 5), and R(6, 7) by a scale factor of -2 and determine the new positions.
💡 Hint: Remember to multiply by -2 and think about the negative scale's flipping effect.
A trapezoid has vertices A(1, 1), B(5, 1), C(4, 4), D(2, 4). Enlarge it by a scale factor of 2. What will be the area of the new trapezoid compared to the original?
💡 Hint: Consider the geometry of the shape first to find the area before enlargement, then apply the scaling.
