Mathematics

Side EF

Step-by-step explanation:

The slope between two point $(x_1,y_1)\ and \ (x_2,y_2)\ is\ given\ as:\\\\$

$slope=\frac{y_2-y_1}{x_2-x_1}$

For triangle ABC with points at A(-2, 1), B(-2, 4), C(1, 1):

$slope\ of\ BC=\frac{1-4}{1-(-2)}=-1\\$

Since, Triangle ABC is similar to triangle DEF, two lines are parallel to each other if they have the same slope. Hence for triangle DEF with D(4,2), E(4,4), F(6,2):

$slope\ of\ DE=\frac{4-2}{4-4}=\infty \\\\slope\ of\ EF=\frac{2-4}{6-4}=-1\\\\slope\ of\ FD=\frac{2-2}{4-6}=0\\$

Since slope of EF = slope of BC, hence side EF is parallel to side BC
