Across
- 2. the extent or measurement of a surface or piece of land.
- 5. figures the angles that have equal measure.
- 6. are formed at corresponding corners when two parallel lines are intersected by a transversal.
- 7. four sided shapes
- 8. the amount of space that a substance or object occupies,
- 9. the ratio of the side opposite the angle we know, or want to know, over the side adjacent to that angle
- 10. a triangle that has two sides of equal length.
- 13. angles are formed at corresponding corners when two parallel lines are intersected by a transversal.
- 15. is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system
- 16. in which one of the interior angles is 90° is called a right triangle
- 17. a closed two dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”
- 18. the continuous line forming the boundary of a closed geometric figure.
- 19. measures the space needed to cover the outside of a three-dimensional shape
Down
- 1. each of the pairs of opposite angles made by two intersecting lines.
- 3. two lines that meet or intersect each other at right angles .
- 4. theorem the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
- 11. defined as the ratio of the side of the angle opposite the angle divided by the hypotenuse
- 12. they share a common shape.
- 14. one shape becomes exactly like another when you move it in some way: turn, flip or slide
- 20. In a right-triangle, cos is defined as the ratio of the length of the adjacent side to that of the longest side
