Basic Geometry
Across
- 1. a portion of the boundary of a circle or a curve
- 2. a part of a line that has a fixed starting point but no endpoint
- 5. a part of a straight line that is bounded by two distinct end points
- 8. two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
- 11. a long square with four congruent sides and four right angles
- 13. an angle that is over 90 degrees is called a _______ angle
- 15. The exponent of a number shows how many times the number is multiplied by itself

- 25. the distance from the centre of the circle to any point on it's circumference
- 26. a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex.
- 27. a centre is a fixed point of all the isometries that move the object onto itself
- 29. the distance or length of the starting and stopping points of a particular line segment
- 31. used to tell exact location in space
- 32. the branch of mathematics concerned with the properties and relations of points, lines, surfaces, solids, and higher dimensional analogs
- 33. a point where two or more curves, lines, or edges meet
Down
- 1. two angles are adjacent if they have a common side and a common vertex
- 3. a one dimensional line that doesnt end

- 10. rise over run
- 12. a four sided plane rectilinear figure with opposite sides parallel
- 14. the sum of two angles that equal 180 are called
- 18. one that’s across from a given angle
- 19. distance from one point on a circle through the centre to another point on the circle
