Since the sum of angles 1 and 2 equals 90°, and they also share same side and same vertex, then, the relationships that describe both angles would be:
B. Complementary angles
C. Adjacent angles
What are Complementary Angles?
Complementary angles are two angles whose sum equals 90 degrees (right angle).
Thus:
m∠1 + m∠2 + 90° = 180° (straight line angle)
m∠1 + m∠2 = 180° - 90°
m∠1 + m∠2 = 90°
Therefore, since the sum of angles 1 and 2 equals 90°, and they also share same side and same vertex, then, the relationships that describe both angles would be:
B. Complementary angles
C. Adjacent angles
