Weegy: They intersect at one point-is true of perpendicular lines.
*** Two lines are said to be perpendicular if they intersect at right angles. Any two perpendicular lines intersect at exactly one point.

19. Two angles are supplementary. The first angle measures 60°. What's the measurement of the second angle?
A. 30°
B. 120°
C. 90°
D. 180°

Two angles are supplementary. The first angle measures 60°, the measurement of the second angle is 120°. supplementary angles sum =180 , one angle =60 , other angle =180-60 =120
