Question

Which relationship describes angles 1 and 2?

Answer 1

1) supplementary angles => sum of angles' measure is 180°


Two lines intersecting creating four angles with the left obtuse angle labeled one and the acute angle to the right labeled two

= > angle 1 +  angle 2 = 180°

Then those two match.


2) complementary angles => sum of the two angles = 90°

Two lines intersecting in a right angle with a square indicating a right angle in quadrant one and a ray splitting quadrant two with a two labeling the left angle and one labeling the angle on the right

=> angle 2 + angle 1 = 90°

Then those two match

3) vertical angles

Two parallel horizontal lines intersected by a vertical line with a square indicating a right angle in quadrant one of the top line and a one labeling the angle in quadrant two and two labeling quadrant four of the top line

Those two matches because the angle label 1 and the angle label 2 are vertical angles as per the definittion.

4) adjacent angles

Two lines intersecting in a V shape with the left angle of one hundred fifty seven degrees and a bottom angle of X degrees

Those two match becasue the angle of 157° and the angle of X° are adjacent.
