Question

1. draw a scaled copy of figure abcd using a scale factor of 1.3.

Explanation:

Step1: Identify vertices of ABCD

Let the vertices of the original figure ABCD be \(A(x_1,y_1)\), \(B(x_2,y_2)\), \(C(x_3,y_3)\), \(D(x_4,y_4)\).

Step2: Apply scale - factor to coordinates

To get the vertices of the scaled - copy with a scale factor of 1.3, use the formula \((x',y')=(1.3x,1.3y)\) for each vertex. So the new vertices are \(A'(1.3x_1,1.3y_1)\), \(B'(1.3x_2,1.3y_2)\), \(C'(1.3x_3,1.3y_3)\), \(D'(1.3x_4,1.3y_4)\).

Step3: Plot the new figure

On the same grid or a new grid, plot the points \(A'\), \(B'\), \(C'\), \(D'\) and connect them in the same order as the original figure ABCD to get the scaled copy.

Answer:

Plot the scaled - copy of figure ABCD with vertices obtained by multiplying the coordinates of the original vertices by 1.3.
