If a ray an angle of a triangle, it divides the opposite side into segments proportional to the lengths of the other two sides. An angle bisector divides an angle into two halves. A perpendicular bisector is the line perpendicular to a segment passing through the segment’s .

bisects, equal, midpoint

Step-by-step explanation:

According to the "Angle Bisector" Theorem, an angle bisector of a triangle divides the opposite side into segments proportional to the lengths of the other two sides of the triangle.

If a ray bisects an angle of a triangle, it divides the opposite side into segments proportional to the lengths of the other two sides. An angle bisector divides an angle into two equal halves. A perpendicular bisector is the line perpendicular to a segment passing through the segment’s midpoint.

x = 3 ± √(5+y)

answer: the up tack or falsum is a constant symbol used to represent a logical constant denoting "false" in logic.
