In a rectangle, all angles are right angles and opposite sides are equal, but not all sides are equal.

In a rectangle, opposite sides are equal and all angles are indeed 90 degrees.

In a rhombus, while all sides are equal and diagonals bisect at right angles, not all angles are right angles.

In a rhombus, while all sides are equal and diagonals bisect each other at right angles, the diagonals are not equal in length.

While the diagonals of a square are equal and bisect each other, they are not necessarily perpendicular to each other in all quadrilaterals.

In an arithmetic progression, the difference between any two consecutive terms is indeed constant, which defines the sequence.

In an equilateral triangle, all sides are equal and all angles measure 60 degrees.

Linear pairs are not equal; they are supplementary, meaning they add up to 180 degrees.

Linear pairs of angles formed by intersecting lines are always supplementary, meaning they add up to 180 degrees.

Angles subtended by the same arc at the circumference of a circle are equal.

Base 8 (octal) is not more efficient than base 2 (binary); it simply represents values in a different way.

Constraints can be both inclusive (allowing certain elements) and exclusive (disallowing others), affecting the composition of the set.

Constraints can be hierarchical, meaning some constraints may take precedence over others in determining set membership.

The statement that 'all constraints must be numerical' is false; constraints can be based on various properties, not just numerical.

The statement a^0 = 0 is false; in fact, a^0 = 1 for any non-zero a.

The statement a^m + a^n = a^(m+n) is incorrect; addition of exponents does not apply in this manner.

A number can have an infinite number of multiples, as you can keep adding the number to itself indefinitely.

A factor of a number is always less than or equal to that number, making the last statement incorrect.

Every number has at least two factors: 1 and the number itself, but some numbers can have more than two factors.

In a geometric progression, the ratio of consecutive terms is indeed constant, which defines the progression.

In a harmonic progression, terms cannot be zero as it would make the reciprocal undefined.

In a harmonic progression, the terms can be negative as long as their reciprocals form an arithmetic progression.

The union of two hybrid sets combines all unique elements from both sets, thus it remains a hybrid set.

All statements are true regarding multiples.

Negative exponents indicate the reciprocal of the base raised to the positive exponent.

Base-2 can represent all integers, as it is a complete positional system.

Different numeral systems can represent the same value, such as the decimal 10 and binary 1010.

Base-2 (binary) is not used in human languages; it is primarily used in computing.

Not all partners have equal say; the partnership agreement can specify different levels of authority.

In a general partnership, partners can be held personally liable for the debts of the business.
