What is a segment bisector?

Back

A segment bisector is a point, line, or segment that divides another segment into two equal parts.

Front

If AB is the segment bisector of PQ, what can be concluded?

Back

PF = QF, meaning the segments PF and QF are equal.

Front

What does it mean if B is the midpoint of AC?

Back

It means that AB = BC, indicating that the two segments are equal.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent.

Front

What does the vertical angles theorem state?

Back

The vertical angles theorem states that vertical angles are congruent, i.e., if <1 and <3 are vertical angles, then <1 ≅ <3.

Front

What must be shown to prove two angles are supplementary?

Back

You must show that the angles add up to 180 degrees.

Front

What is an angle bisector?

Front

What is a linear pair of angles?

Back

A linear pair of angles are two adjacent angles that form a straight line, and their measures add up to 180 degrees.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.
