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.
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.
