Students get to practice measuring angles using built-in protractors in this fun geometry activity! After measuring, they'll put their angle knowledge to the test by classifying each angle as acute, obtuse, right, or straight. They are all congruent to each other. ∠1 ≅ ∠4 are vertical angles. ∠4 ≅ ∠5 are alternate interior angles, and ∠5 ≅ ∠7 are vertical angles. The same reasoning applies to the obtuse angles in the figure: ∠2, ∠3, ∠6, and ∠8 are all congruent to each other.
