12/9 Perp Bisectors

Front

What is a perpendicular bisector?

Back

A line that divides another line segment into two equal parts at a 90-degree angle.

Front

What does the word BISECT mean?

Back

To cut something into two congruent pieces or in half.

Front

If GC is 11, what is AG?

Back

11 (because AG is equal to GC in a perpendicular bisector).

Front

Find the length of AD if AD is a segment bisected by point D and the total length is 16.

Back

8 (AD = total length / 2).

Front

What is the circumcenter of a triangle?

Back

The point where the perpendicular bisectors of the sides of the triangle intersect.

Front

If AB = 10 and point C is the midpoint, what is AC?

Back

5 (AC = AB / 2).

Front

Find SV if SV is a segment bisected by point T and the total length is 36.

Back

18 (SV = total length / 2).

Front

What is the relationship between the circumcenter and the vertices of a triangle?

Back

The circumcenter is equidistant from all three vertices of the triangle.

Front

If a line segment is bisected, what can be said about the two resulting segments?

Back

They are congruent (equal in length).

Front

What is the formula to find the length of a segment if you know the total length and it is bisected?

Back

Length of each segment = Total length / 2.
