ng-repeat-start and ng-repeat-end are directives in the AngularJS framework. They are used in conjunction to repeat a block of HTML elements. This is particularly useful when you need to repeat a group of elements that cannot be directly wrapped by a single element, such as repeating a `<tr>` element within a `<table>` without introducing an extra `<tr>` tag.

The ng-repeat-start directive is placed on the first element of the block you wish to repeat. AngularJS will then clone this element and all subsequent elements up to the ng-repeat-end directive for each item in the collection specified in the directive's expression. The ng-repeat-end directive marks the end of the repeating block.

For example, if you have a table and want to repeat rows, you might use ng-repeat-start on the `<tr>` tag and ng-repeat-end on the closing `</tr>` tag. This ensures that the repeating content is correctly structured within the table's `<tbody>`.

When the directive iterates over the collection, it creates separate instances of the HTML block, each bound to a specific item from the collection. This allows for dynamic generation of complex HTML structures based on data. It's a more flexible alternative to the standard ng-repeat directive when dealing with repeating elements that cannot be contained within a single parent element due to HTML structure constraints.
