Across
  1. 3. the sum of the measures of the interior angles of a triangle is always 180°
  2. 4. a triangle with at least two congruent sides
  3. 7. given a line and a point not on the line, there is one and only one line that contains the given point and is parallel to the given line.
  4. 10. angles outside the parallel lines and are on diagonal opposite sides of the transversal line
  5. 14. an angle inside a triangle that is not adjacent to a given exterior angle
  6. 15. two angles whose measures add to 180°
  7. 16. two angles that have a common side and the same vertex, and their other sides point in opposite directions
  8. 17. any angle on the inside of a polygon
Down
  1. 1. opposite angles formed by intersecting lines
  2. 2. angles in between the parallel lines and are on diagonal opposite sides of the transversal
  3. 5. angles in between the parallel lines and are on the same side of the transversal
  4. 6. a triangle with three congruent sides
  5. 8. a line that intersects two or more lines in a plane
  6. 9. two angles whose measures add to 90°
  7. 11. any angle on the outside of a polygon, formed by two sides of a polygon extending outside the polygon
  8. 12. angles that lie in corresponding positions when a transversal intersects two parallel lines
  9. 13. a conditional statement that switches the hypothesis and the conclusion of the original conditional statement
