Across
- 3. The quality of being made up of exactly similar parts facing each other or around an axis
- 7. an obtuse angle is greater than 90 degrees but is less than 180 degrees
- 10. a number, as of years, days, or minutes, representing an interval.
- 12. the perimeter of a circle.
Down
- 1. the side of a right-angled triangle opposite the right angle. The hypotenuse is the longest side of a right-angled triangle.
- 2. gives the relationship between the lengths of the sides of a right angled triangle. The theorem states: In a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
- 4. the amount of space occupied by an object.
- 5. the line segment that includes the center and whose endpoints lie on the circle.
- 6. a measure of the force that gravity exerts on a body.
- 8. an angle whose measure is between 0-90 degrees
- 9. an angle that measures exactly 90 degrees.
- 11. two angles in the same plane that have a common vertex and a common side, but no common interior points.
- 13. a set of points on a plane that are equidistant from a given point (its center).
