What is an angle bisector?

Back

An angle bisector is a line or ray that divides an angle into two equal parts.

Front

What is a perpendicular bisector?

Back

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

Front

What is a median in a triangle?

Back

A median is a line segment that connects a vertex of a triangle to the midpoint of the opposite side.

Front

What is a midsegment in a triangle?

Back

A midsegment is a segment that connects the midpoints of two sides of a triangle.

Front

What is the triangle inequality theorem?

Back

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

If PQ is the perpendicular bisector of MN, what can be said about the lengths of MP and PN?

Back

MP = PN; they are equal in length.

Front

What is the relationship between the angles formed by an angle bisector?

Back

The angles formed by an angle bisector are congruent.

Front

How do you determine if three lengths can form a triangle?

Back

Use the triangle inequality theorem: check if the sum of the lengths of any two sides is greater than the length of the third side.

Solve for x: 2x + 4 = 24.

Back

x = 10.

Front

Find the length of AB if A(1,2) and B(4,6).

Back

Length of AB = √((4-1)² + (6-2)²) = 5.
