1. For triangle ABC with vertices A(2, 1), B(4, 3), C(1, 5), apply a dilation centered at the origin with scale factor 2: multiply each coordinate by 2 to get A'(4, 2), B'(8, 6), C'(2, 10). Plot these points and connect them to form the dilated triangle.
2. For triangle MNP with vertices M(-2, -1), N(0, 3), P(2, -1), apply a dilation centered at the origin with scale factor 1/2: multiply each coordinate by 1/2 to get M'(-1, -0.5), N'(0, 1.5), P'(1, -0.5). Plot these points and connect them to form the dilated triangle.
3. For triangle JKL with vertices J(-4, 2), K(-2, -2), L(0, 4), apply a dilation centered at the origin with scale factor 1/2: multiply each coordinate by 1/2 to get J'(-2, 1), K'(-1, -1), L'(0, 2). Plot these points and connect them to form the dilated triangle.
4. For triangle RST with vertices R(1, 1), S(3, 1), T(2, 3), apply a dilation centered at the origin with scale factor 3: multiply each coordinate by 3 to get R'(3, 3), S'(9, 3), T'(6, 9). Plot these points and connect them to form the dilated triangle.
Parent Tip: Review the logic above to help your child master the concept of dilations on a coordinate plane worksheet.
