In a set of points, what is the geometric interpretation of the union of two sets?

  1. Intersection of the two sets

  2. Area of the two sets combined

  3. Combined perimeter of the two sets

  4. Region containing all points belonging to either set


Correct Option: D
Explanation:

The union of two sets is the set of all elements that are in either set, geometrically represented as the region containing all points belonging to either set.

Consider two sets of points in a plane. What geometric shape is formed by the intersection of these two sets?

  1. Union of the two sets

  2. Convex hull of the two sets

  3. Region containing points common to both sets

  4. Complement of the two sets


Correct Option: C
Explanation:

The intersection of two sets is the set of all elements that are in both sets, geometrically represented as the region containing points common to both sets.

Given a set of points in a plane, what geometric shape is formed by the convex hull of the set?

  1. Union of the set and its complement

  2. Smallest convex set containing all points in the set

  3. Intersection of the set and its complement

  4. Complement of the set


Correct Option: B
Explanation:

The convex hull of a set of points is the smallest convex set containing all points in the set, geometrically represented as the smallest convex polygon enclosing all points in the set.

In a set of points in a plane, what geometric shape is formed by the complement of the set?

  1. Union of the set and its convex hull

  2. Region containing points not belonging to the set

  3. Intersection of the set and its convex hull

  4. Region containing points inside the convex hull of the set


Correct Option: B
Explanation:

The complement of a set is the set of all elements that are not in the set, geometrically represented as the region containing points not belonging to the set.

Consider a set of points in a plane. What geometric shape is formed by the boundary of the convex hull of the set?

  1. Union of the set and its complement

  2. Smallest convex set containing all points in the set

  3. Intersection of the set and its complement

  4. Convex polygon enclosing all points in the set


Correct Option: D
Explanation:

The boundary of the convex hull of a set of points is the convex polygon enclosing all points in the set.

In a set of points in a plane, what geometric shape is formed by the interior of the convex hull of the set?

  1. Union of the set and its complement

  2. Smallest convex set containing all points in the set

  3. Intersection of the set and its complement

  4. Region inside the convex polygon enclosing all points in the set


Correct Option: D
Explanation:

The interior of the convex hull of a set of points is the region inside the convex polygon enclosing all points in the set.

Given a set of points in a plane, what geometric shape is formed by the closure of the set?

  1. Union of the set and its boundary

  2. Smallest closed set containing all points in the set

  3. Intersection of the set and its boundary

  4. Complement of the set


Correct Option: A
Explanation:

The closure of a set is the union of the set and its boundary, geometrically represented as the smallest closed set containing all points in the set.

In a set of points in a plane, what geometric shape is formed by the boundary of the closure of the set?

  1. Union of the set and its complement

  3. Intersection of the set and its complement

  4. Set of points that are not in the interior of the set


Correct Option: D
Explanation:

The boundary of the closure of a set is the set of points that are not in the interior of the set.

Consider a set of points in a plane. What geometric shape is formed by the interior of the closure of the set?

  2. Smallest closed set containing all points in the set

  3. Intersection of the set and its complement

  4. Region inside the set and its boundary


Correct Option: D
Explanation:

The interior of the closure of a set is the region inside the set and its boundary.

Given a set of points in a plane, what geometric shape is formed by the complement of the closure of the set?

  1. Union of the set and its complement

  2. Smallest closed set containing all points in the set
