Question

equal symbol = equal means equal measurement (numerically) numbers used to show segments are equal dc = de = congruent symbol ≅ congruent means same shape, same size tick - marks used to show segments are congruent dc ≅ de

Explanation:

Step1: Equal symbol

The standard equal symbol is "$=$".

Step2: Equal means in measurement

Equal means equal in length.

Step3: Calculate DC

DC is labeled 14, so $DC=14$.

Step4: Calculate DE

DE = DC + CE, DC=14, CE=14, so $DE=14+14=28$.

Answer:

$=$, length, 14, 28
