Practice Questions

Test your understanding with targeted questions

Question 1 Easy

What is the new position of point A(1,1) after enlarging by a scale factor of 3?

💡 Hint: Multiply both coordinates by 3.

Question 2 Easy

After reflecting point B(2, 3) across the x-axis, what are the new coordinates?

💡 Hint: Remember to change the sign of the y-coordinate.

Question 1

What does the scale factor determine during enlargement?

The shape orientation
The new size
The color of the shape

💡 Hint: Think about how size changes with multiplication.

Question 2

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given triangle JKL with vertices J(2, 2), K(4, 1), L(3, 5), first enlarge by a scale factor of 1.5, then rotate 90 degrees CCW. What are the final coordinates?

💡 Hint: First enlarge by 1.5, and then apply the rotation rules.

Challenge 2 Hard

If a pentagon is enlarged by a factor of -2 and reflected over the y-axis, what is the effect on the coordinates of its vertices, initially at A(-2, 2), B(-1, 1), C(1, 1), D(1, -1)?

💡 Hint: Negate each coordinate during enlargement and apply reflection after.
