Question

Find the coordinates of the vertices of polygon H´J´K´L´ after polygon HJKL is dilated using the given scale factor. H(–1, –6), J(1, –3), K(–5, –1), and L(5, –5); scale factor 3

Answer 1

• H' (-3, -18)

• J' (3, -9)

• K (-15, -3)

• L = (15, -15)

Explanation:

Given:

H(–1, –6), J(1, –3), K(–5, –1), and L(5, –5)

We know that polygons are HJKL relaxes using the scale factor 3. This means that, to find the coordinates of the vertices of the polygon H'J'K'L ', we need to multiply the coordinate system x and y coordinates of each vertex by a factor of 3 proportion as following:

• H' = (-1*3, -6*3) = (-3, -18)

• J' = (1*3 , -3*3) = (3, -9)

• K = (-5*3, -1*3) =(-15, -3)

• L = (5*3, -5*3) = (15, -15)
