Question

Consider the paragraph proof.

Answer 1

Applying the distance formula, DE = a. Therefore, the missing information is: A. a.

What is the Distance Formula?

Distance Formula for determining the distance between two points on a coordinate plane is given as: $d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}$.

In the proof given, applying the distance formula to find DE, we have:

DE = √[(a + b -  b)² +  (c - c)²}

Simplifying this, we would have:

DE = √(a² + 0²) = √(a²)

DE = a

Therefore, the missing information in the proof is: A. a.
