Alternate Interior Angles Theorem (V1)

Home Alternate Interior Angles Theorem (V1)

How it works ?
  1. In the applet below, a TRANSVERSAL intersects 2 PARALLEL LINES.
  2. When this happens, there are 2 pairs of ALTERNATE INTERIOR ANGLES that are formed.
  3. Interact with the applet below for a few minutes, then answer the questions that immediately follow.

Directions & Questions:

1) Complete the following statement: If a transversal intersects 2 ________________ ______________, then alternate interior angles are _____________________.

2) If the pink angle above measures 134 degrees, what would the measure of its alternate interior angle be?
