what is the justification of m angle 1 + m angle 2 = 90degree
The justification for the sum of the angles 1 and 2 being equal to 90 degrees is based on the concept of complementary angles. Complementary angles are two angles whose measures add up to 90 degrees.
To show why the sum of angle 1 and angle 2 equals 90 degrees, we need to gather more information about these angles. Is there any given information or a diagram that describes the relationship between these angles?
