What is bc ?

enter your answer in the box.

BC= 8 units.

Step-by-step explanation:

In the given figure m, we have a Δ ABC in which point D and F are the mid point of sides AB and AC respectively .

We know that the Mid - segment theorem says that a line segment that connects the midpoints of two sides of a triangle is parallel to the third side and it should be equal to one-half of the third side.

Therefore , For the given situation , we have

Since DF = 4 units [Given ]

Then,  

Hence, BC= 8 units.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.
