<p><strong>Concept:</strong></p><p>A linear pair is formed when two adjacent angles share a common verte× and a common arm, and their non-common arms form a straight line.</p><p><strong>Property:</strong></p><p>The sum of the angles in a linear pair is always equal to 180 degrees.</p><p><strong>E×planation:</strong></p><p>Since the non-common arms of the two adjacent angles in a linear pair form a straight line, the measure of the angle formed by these non-common arms is 180 degrees. The two adjacent angles together constitute this straight angle.</p><p>Therefore, if the measures of the two angles in a linear pair are ∠1 and ∠2, then:</p><p>∠1 + ∠2 = 180°</p><p><strong>∴ The sum of angles of a linear pair is 180°.</strong></p> - www.domiterapia.com
