Respuesta :
The angle show with the yellow square has a measure of 90°.
Together with angles 1 and 2, they form a straight angle so we have:
∠1+∠2+90°=180°,
subtracting 90° from both sides we have:
∠1+∠2=90°
If the sum of the measures of 2 angles is 90°, the angles are called complementary.
Since the sum of the measures of angles 1 and 2 is 90°, then these 2 angles are complementary.
Answer: They are complementary
Together with angles 1 and 2, they form a straight angle so we have:
∠1+∠2+90°=180°,
subtracting 90° from both sides we have:
∠1+∠2=90°
If the sum of the measures of 2 angles is 90°, the angles are called complementary.
Since the sum of the measures of angles 1 and 2 is 90°, then these 2 angles are complementary.
Answer: They are complementary
Based on the provided information, statement that is true about angles 1 and 2 is that they are complementary.
What is complementary angle?
complementary angle can be explained as two angles are that has their measures adding to 90 degrees.
We can see that coloured portion is 90°, and addition of ∠1 and ∠2= 90° since they are on straight line.
Therefore, option C is correct.
