Across
  1. 3. Angle I’m larger than 90°, but smaller than 180°. What kind of angle am I?
  2. 7. I’m a four-sided polygon. What am I?
  3. 8. I measure the distance around a shape. What am I?
  4. 9. I go from the center of a circle to any point on the circle. What am I?
  5. 13. I’m a closed shape made of straight lines. What kind of shape am I?
  6. 14. I describe figures that are the same in shape and size. What word am I?
  7. 15. I measure how much space a 3D object takes up. What am I?
  8. 18. I extend forever in both directions and have no thickness. What am I?
  9. 19. I measure how much space a shape covers. What am I?
  10. 20. I start at a point and extend forever in one direction. What am I?
  11. 21. Angle I’m smaller than a right angle. What kind of angle am I?
Down
  1. 1. Angle I look like a straight line and measure 180°. What kind of angle am I?
  2. 2. Lines I never touch, no matter how far you extend me. I stay the same distance apart. What am I?
  3. 4. I describe figures with the same shape but not necessarily the same size. What word am I?
  4. 5. Every point on me is the same distance from the center. What am I?
  5. 6. I pass through the center of the circle and touch both sides. I'm twice the radius. What am I?
  6. 8. I have no size, no shape, but I mark a location in space. What am I?
  7. 9. Angle I measure exactly 90 degrees. What kind of angle am I?
  8. 10. Area I measure the total area of all the faces of a 3D shape. What am I?
  9. 11. Lines I intersect at a right angle. What am I?
  10. 12. I’m formed by two rays with a common endpoint. What am I?
  11. 16. Segment I have two endpoints and all the space between them. What am I?
  12. 17. I’m a polygon with exactly three sides. What shape am I?
  13. 22. – I’m a line segment with both endpoints on the circle, but I don’t have to go through the center. What am I?
