- 3. when we use pencil, a ruler and compasses in maths to create a shape or split something in half
- 6. up and down
- 7. a line that cuts through a circle but is not the diameter
- 8. when we rotate something to the right
- 10. when we rotate something to the left
- 12. which way we turn something
- 13. the portion of a circle enclosed by two radii and an arc
- 14. on a graph, we have the y ____ and the x ____
- 16. represented by this symbol: √
- 18. a rule in algebra or other branches of mathematics expressed by symbols or formulae
- 19. a straight line that goes from edge to edge of a circle and passes through the centre
- 20. the middle point of a circle
- 22. one of the four transformations, we move shapes around a point and we might use tracing paper
- 23. the technical term for splitting an angle in half
- 26. the Greek who came up with the rule we use for right angled triangles, he also has a famous cup
- 27. a word to describe a shape being an exact reflection on both sides of a mirror line
- 28. we find the area of this shape with the formula b x h x 0.5
- 30. a portion of the circumference
- 31. one of the four transformations, we use a mirror line
- 33. the outer edge of a circle
- 34. a straight line that touches a circle at a single point but does not cross the circumference
- 35. we use it to find the area and circumference of circles, Miss Reggler has it on her badge
- 36. a word to describe when something is round
- 38. the side of a triangle opposite the right angle, we label it c
- 39. we find the area of this using the formula πr²
- 41. we find the area of this shape with the formula (a+b)x h x 0.5
Down
- 1. the technical term for splitting a line in half
- 2. the distance from the centre of a circle to the outer edge of a circle
- 4. we use this when we are performing a translation, the horizontal movement is on the top and the vertical movement is on the bottom
- 5. a word used to describe translation, reflection, rotation and enlargement
- 9. what we reflect in
- 11. one of the four transformations, shapes will increase or decrease in size when we do this
- 15. part of a circle made when it is cut by a line
- 17. we find the area of this shape with the formula b x h and the angles of this shape are all right angles
- 21. we find the area of this shape with the formula b x h and while it can be a rectangle, it does not have to be
- 24. when we multiply a number by itself
- 25. one of the four transformations, we use column vectors to describe the movement
- 29. left and right
- 31. when a triangle has an angle that it 90 degrees, we call it a __________ triangle
- 32. we find the area of this by calculating πr² and then dividing the answer by 2
- 37. the word to describe when a shape is made up of more than one simple shape
- 40. the space a shape takes up, we use units like cm² and m²
