Across
  1. 4. All sides are equal
  2. 5. Two angles are called supplementary when their measures add up to 180 degrees.
  3. 6. In concave quadrilaterals, one interior angle is greater than 180 degrees.
  4. 8. Opposite sides are parallel.
  5. 9. Is a simple quadrilateral with two pairs of parallel sides.
  6. 10. All angles are equal and measure 90 degrees.
  7. 12. Is a line segment that joins two opposed polygonal vertices (or corners).
  8. 13. The figure in which two rays intersect at the vertex, or common point, is referred to as an angle.
  9. 15. Is a piece of a straight line with two clearly defined end points as its boundaries.
Down
  1. 1. In geometry, congruent means identical in shape and size.
  2. 2. An angle bisector is a ray or a line that divides an angle into two equal parts.
  3. 3. Is described as a polygon with four sides. The endpoints are referred to as vertices, while the sides are known as segments.
  4. 7. Imply that two objects are different from one another in a way that identifies a specific type of relationship.
  5. 11. In Geometry, two angles are adjacent if they have a common side and a common vertex.
  6. 14. One pair of opposite angles are equal.
