Across
  1. 1. How often something happens compared to the total number of trials.
  2. 3. A branch of maths that deals with triangles and the relationships between their sides and angles.
  3. 5. A number between 0 and 1 that shows how likely something is to happen.
  4. 6. When one event doesn’t affect the chance of another happening.
  5. 9. A trigonometric ratio that compares the adjacent side to the hypotenuse in a right triangle.
  6. 13. When one event doesn’t change the chance of another happening.
  7. 14. Making a shape bigger (or smaller) while keeping its proportions the same.
  8. 18. A diagram with overlapping circles that shows how different groups share or differ
  9. 20. Putting something back after choosing it, so it could be picked again.
  10. 21. A flat, two-dimensional shape like a triangle or rectangle.
  11. 23. A sentence that links two ideas using words like “if”, “then”, or “given”.
  12. 26. A logical explanation that shows something is always true.
  13. 28. Two events that add up to 100% — if one happens, the other can’t.
  14. 30. The chance of something happening based on actual results or trials.
  15. 31. Events that share some outcomes — they overlap.
  16. 32. A branching diagram that shows all possible outcomes step by step.
  17. 33. When shapes have the same shape but different sizes.
  18. 34. Using facts and rules to solve problems or prove something is true.
  19. 36. Angles in matching positions when two lines are crossed by another line.
  20. 37. Angles on opposite sides of a line that are equal when lines are parallel.
  21. 38. The full list of all possible outcomes in a chance experiment.
Down
  1. 2. A chance experiment with two parts, like flipping a coin and then rolling a die.
  2. 4. Triangles that are exactly the same size and shape.
  3. 7. Rules about angles, like how angles in a triangle always add up to 180°.
  4. 8. The chance of something happening based on maths and logic, not experiments.
  5. 10. Angles on the same side of a line that add up to 180° when lines are parallel.
  6. 11. A trigonometric ratio that compares the opposite side to the adjacent side in a right triangle.
  7. 12. A formula that helps you find the area of any triangle using sine and two sides.
  8. 15. A number that shows how much a shape has been enlarged or reduced.
  9. 16. An angle formed outside a shape when one side is extended.
  10. 17. A situation where you don't know what will happen, but you can list all the possible outcomes.
  11. 19. The study of shapes, angles, and space.
  12. 22. Events that can’t happen at the same time
  13. 24. Two angles that add up to 180°.
  14. 25. A trigonometric ratio that compares the opposite side to the hypotenuse in a right triangle.
  15. 27. A grid used to show all possible outcomes in a chance experiment.
  16. 29. A drawing that shows all the possible outcomes of a chance experiment step by step.
  17. 35. A way to organize data or outcomes in rows and columns for easy reading.
