- 4. A shape that has ten sides and ten vertices. The interior angles add up to 1440 degrees.
- 8. A rectangle with 4 sides that have the same length. The interior angles add to 360 degrees.
- 10. A shape that has six vertices and six sides. The interior angles add up to 720 degrees.
- 11. A triangle that has three different side and angle measurements. The angles add up to 180 degrees.
- 13. A shape that has four sides. One pair of the sides are parallel and one side isn't.
- 14. A traingle that have all sides equal. They also have all angles equal.
- 16. A shape that has 5 sides and 5 vertices.The interior angles add up to 540 degrees.
- 18. A position in space that is represented using a dot.It has no dimension.
- 20. Angles that are on the same side of the transversal. They have to be in the same position.
Down
- 1. An angle that measures 90 degrees. It's exactly half of a straight angle.
- 2. A shape that has eight sides and eight vertices. The interior angles add up to 1080 degrees.
- 3. An line, ray or segment that will divide an angle into two parts. The two angles will be congruent.
- 5. An angle that is less than 90 degrees. It has to be more than 0 degrees.
- 6. Line segments that don't intersect. A trapezoid has one pair of these lines.
- 7. A shape that has no edges or vertices.You can use 2(pi)radius to find its circumference.
- 9. A polygon that has 4 sides. Some examples are squares, rectangles, and trapezoids.
- 12. A shape that has three vertices and three sides.The interior angles add up to 180 degrees.
- 15. A parallelogram with 4 right angles. A square can also be this shape.
- 17. A shape that has nine sides and nine vertices. The interior angles add up to 1260 degrees.
- 19. If two triangles all have congruent sides then the triangles are congruent. This congruence statement is a postulate.
