Math Problem Statement

Name one angle congruent to ∠7.

Solution

The image you provided appears to be related to parallel lines and transversals, where you need to identify one angle congruent to angle ∠7.

In this case, angle ∠7 lies at the intersection of the transversal line with the horizontal line, and you are asked to find a congruent angle.

Looking at the diagram:

  • Angle ∠7 is congruent to angle ∠5 because these angles are alternate interior angles formed by the transversal intersecting the two parallel lines. By the Alternate Interior Angle Theorem, alternate interior angles are congruent when the lines are parallel.

So, the correct answer is:

  • ∠5 ≅ ∠7

  4. Can you explain the difference between alternate exterior angles and alternate interior angles?
  5. How can you use vertical angles in parallel line problems?

Tip: When working with parallel lines and transversals, always look for congruent angles, such as alternate interior angles, corresponding angles, and vertical angles, to simplify your problem-solving process.
