Ana made a zip line for her tree house. To do this, she attached a pulley cable. She then strung the cable at an angle between the tree house and another tree. She made the drawing of the zip line at the left. The two trees are parallel. What is the measure of angle 1 and are angle 1 and the given angle same-side interior angles, alternate interior angles, or corresponding angles?

The medians of a triangle intersect in a point that is two-thirds the distance from each vertex to the midpoint of the opposite side
The perpendicular bisectors of the sides of a triangle intersect in a point that is equidistant from the three vertices of the triangle. This construction is used to circumscribe a circle.
A line that contains the midpoints of one side of a triangle and is parallel to another side passes through the midpoint of the third side
