It is always a good practice to name the features to make them easier to find, recognize and understand, at least the most important features and parameters.
Sometimes it might be also preferred to name the constraints within a sketch, especially in case of very complex sketches. To modify and display a name of any dimension follow these steps.
1. Create a constrain and go to it's properties - Fig.1.
2. Change the Feature Name in the Feature Properties tab - Fig.2.

3. To display the name click RMB on the constrain, open the ... object tab and choose Name/Value Display. Three settings are available - Name Display, Value Display and Name/Value Display.
4. The name and the value of a constrain have been shown - Fig.3.
