Geometry 2

2. the distance around a circle or any curved shape, calculated using the formula C=πd
3. a closed 2D shape with straight edges & corners named by their sides (ex. square, rectangle, hexagon etc.)
5. a new set containing all distinct elements from all the original sets, essentially combining them and removing duplicates
7. a set where all its elements are also contained within a larger set
11. refers to the common elements, points, or regions shared by two or more mathematical objects (like sets, lines, or curves), represented by the symbol '∩'
13. events where the outcome of the first event changes the probability for the second event
14. ratio of the opposite side to the adjacent angle in a right triangle

1. a U-shaped curve with two branches
3. the branch of math studying likelihood of events, measured 0 (impossible) to 1 (certain), calculated as favorable outcomes over total outcomes
4. a solid geometric figure with straight parallel sides & a circular or oval cross section
6. two or more events where the occurrence of one has no effect on the probability of the others happening
8. a closed, oval-shaped curve defined as the set of all points where the sum of the distances to two fixed points (foci) is constant, appearing as a stretched circle
9. ratio of the adjacent side to the hypotenuse in a right triangle
10. a solid or hollow object with a circular base & triangular structure
12. ratio of the side opposite a given angle to the hypotenuse in a right triangle
