Across
- 1. angle with a measure greater than 90 but less than 180.
- 5. quadrilateral with exactly one pair of parallel sides
- 6. a circle is a geometric line segment whose endpoints both lie on the circle. A secant line, or just secant, is the line extension of a chord. More generally, a chord is a line segment joining two points on any curve, for instance an ellipse. A chord that passes through a circle's center point is the circle's diameter.
- 10. quadrilateral with two pairs of parallel sides
- 14. is a branch of mathematics that deals with the scientific collection, organization, presentation, analysis and interpretation of numeral data in order to obtain useful and meaning information.
- 15. a line that is coplanar with the circle and intersects the circle in exactly one point.
- 16. is a algebraic expression that is a sum of 2 or more terms.
- 18. parallelogram with four congruent sides.
- 19. the union of three or more coplanar segments which intersect at end points,with each end point shared by only two non collinear segments.
Down
- 2. aline thet intersects the Circle in two points.
- 3. error an unavoidable error the results from chance variations in the measurement caused by changes in presures and temperature.
- 4. mass the mas of an object is measured by means of a force everted by the earth gravitation or the weight.
- 7. is measured in square units a square unit is a square with a side 1 unit in length.
- 8. our sided polygon
- 9. angle with a measure of 90.
- 11. angle with a measure greater that 0 but less than 90.
- 12. parallelogram witj four right angels.
- 13. the union of two noncollinear rays with a common endpoint
- 16. the quantity with the most number of frequency.
- 17. polya (1887-1985) a Hungarian american mathematics educator,believed that problem solving was an art, and that w/ practice it could be mastered for simple steps to solve a problem: read,plan solve and check.
