challenge #1
fill in the missing words
to help find the measure of angle 1, 2 and y we need to notice the angle relationships. the first angle relationship we notice is \boxed{} angles which we know are \boxed{} (i.e. equal in measure). the other angle relationship is the \boxed{} of the \boxed{} angles of a triangle. we know that if we add all the angles in a triangle they will add to \boxed{} degrees.

Explanation:

• Vertical angles are opposite intersecting angles, so the 38° angle matches angle 1, and 41° matches angle 2.
• The sum of the interior angles of any triangle always equals 180°, which is used to solve for the unknown angle \( y \).

Answer:

1. vertical
2. 38° and 41°
3. sum
4. interior
5. 180
