Answer:
If the angles 1 and angle 2 are supplementary then the equation which represents the relationship between their measures is given by : m∠1 + m∠2 = 180°
Explanation:
Any two angles are called supplementary if and only if the measure of sum of their angles is 180°
⇒ For any two angles to be supplementary their sum of the measure of the angles should be 180°
Now, it is given that the angles 1 and angle 2 are supplementary.
⇒ Sum of the measure of their angles is 180
Now, we need to find a equation that represents the relation between their measures
⇒ The required relationship of their measures is : m∠1 + m∠2 = 180°
Hence, if the angles 1 and angle 2 are supplementary then the equation which represents the relationship between their measures is given by : m∠1 + m∠2 = 180°
