You're correct
Answer:
Side, Side, Side
Step-by-step explanation:
If 3 sides in one triangle are congruent to 3 sides in another triangle, then the triangles are congruent. This is called the Side-Side-Side (SSS) Postulate and it is a shortcut for proving that two triangles are congruent.

To find the length of a line given two points, we are going to use the distance formula, which is defined below:

(
and
are the two points)
The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:

- Substitute values into formula

- Combine like terms and then simplify
to 0

- Compute


- Compute

The length of DC is 3.
