By Pythagoras, c² = 6² + 8² = 100.
Thus, c = 10 cm.

For a right triangle, the square of the longest side equals the sum of the other squares.
Here, 5² + 12² = 13².

An exterior angle equals the sum of the two remote interior angles.
It is supplementary to the adjacent interior angle.

A quadrilateral can be divided into two triangles.
Thus, its angle sum is 2 × 180° = 360°.

A rectangle has four right angles and opposite sides equal.
Its diagonals are also equal in length.

A rhombus is defined by four equal sides.
Its angles need not be right angles.

All three angles are equal and their sum is 180°.
Therefore, each angle is 180° ÷ 3 = 60°.

Equal sides in an isosceles triangle face equal angles.
This is the base-angle theorem.

When multiplying powers with the same base, add the exponents.
Thus, a³ × a⁵ = a⁸.

When dividing powers with the same base, subtract the exponents.
Thus, x⁷ ÷ x³ = x⁴.

Square the coefficient and multiply the exponent by 2.
This gives 2²a⁶ = 4a⁶.

An exponent of 1/2 represents a square root.
Thus, 16^(1/2) = √16 = 4.
