If triangle ABC = triangle EDF where the coordinates of A(-1, 1), B(2,4), and C(3,1), what is the measure of EF?

The measure of EF is 4 units

Step-by-step explanation:

If triangle ABC = triangle EDF where the coordinates of A(-1, 1), B(2,4), and C(3,1), what is the  measure of EF?

To find the measure of EF, we will follow the steps below;

since  triangle ABC = triangle EDF  the coordinates of  triangle ABC  are A(-1, 1), B(2,4), and C(3,1),  then the coordinates of triangle EDF are E(-1, 1), D(2,4), and F(3,1)

To find the measure of EF, we will use the distance formula;

|EF| = √(x₂-x₁)² + (y₂-y₁)²

E(-1, 1)   F(3,1)

x₁=-1

y₁=1

x₂ =3

y₂ = 1

We can now proceed to substitute the values into the formula;

|EF| = √(3+ 1)² + (1-1)²

      = √(4)² + (0)²

      = √(4)²

       =√16

        =4

The measure of EF is 4 units

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
