Question

decide if this biconditional statement is true or false. two angles form a linear pair if and only if they are adjacent and add up to 180°. true false

Explanation:

Step1: Analyze the forward implication

If two angles form a linear pair, by definition, they are adjacent and their measures add up to \(180^{\circ}\).

Step2: Analyze the reverse implication

If two angles are adjacent and their measures add up to \(180^{\circ}\), then they form a linear pair. This is also in line with the geometric definition of a linear pair.

Answer:

True
