1. Graph the image of △ABC after a dilation with a scale factor of 2, centered at the origin.
- Original points: A(1,1), B(3,1), C(1,4)
- Multiply each coordinate by 2: A'(2,2), B'(6,2), C'(2,8)
- Plot A', B', C' and connect them to form the dilated triangle.
2. Graph the image of △MNP after a dilation with a scale factor of 1/2, centered at the origin.
- Original points: M(-2,2), N(0,4), P(2,2)
- Multiply each coordinate by 1/2: M'(-1,1), N'(0,2), P'(1,1)
- Plot M', N', P' and connect them to form the dilated triangle.
3. Graph the image of △JKL after a dilation with a scale factor of 1/2, centered at the origin.
- Original points: J(-4,4), K(-4,-2), L(0,-2)
- Multiply each coordinate by 1/2: J'(-2,2), K'(-2,-1), L'(0,-1)
- Plot J', K', L' and connect them to form the dilated triangle.
4. Graph the image of △PQT after a dilation with a scale factor of 3, centered at the origin.
- Original points: P(-1,1), Q(1,1), T(0,-1)
- Multiply each coordinate by 3: P'(-3,3), Q'(3,3), T'(0,-3)
- Plot P', Q', T' and connect them to form the dilated triangle.
Parent Tip: Review the logic above to help your child master the concept of reflecting points on a coordinate plane worksheet.
