explanation: The text extract is a description of a lecture series on geometry from Khan Academy, taught by Prof. Salman Khan. It provides an overview of the topics covered in the lectures, including angles, parallel lines, similar triangles, area and perimeter, circles, the Pythagorean Theorem, special right triangles, Heron's Formula, and more. The specific lecture mentioned is "Heron's Formula," which focuses on using Heron's Formula to determine the area of a triangle given the lengths of its sides. The extract does not contain a question or an answer.
distilabel_metadata.content: Evaluate the user given text extract and determine if it contains a math question and optionally and answer to this question.
  
  Output rules:
  
  1. Briefly describe the document and mention if it contains a question or a question and answer.
  2. Finalize the output with: Label: no-question,question,question-and-answer,multiple-question,multiple-question-and-answer
