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 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

What is the range of possible lengths for the third side of a triangle with sides of lengths 7 ft and 13 ft?

Back

The length of the third side must be more than 6 ft but less than 20 ft.

Front

What does the Exterior Angle Inequality Theorem state?

Back

The Exterior Angle Inequality Theorem states that the measure of an exterior angle of a triangle is greater than the measures of the two non-adjacent interior angles.

Front

What is an angle bisector?

Back

An angle bisector is a ray that divides an angle into two equal angles.

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 an altitude in a triangle?

Back

An altitude is a perpendicular segment from a vertex to the line containing the opposite side.

Front

What is a triangle?

Back

A triangle is a polygon with three edges and three vertices.

Front

What is the definition of a triangle's side length?

Back

The side length of a triangle is the distance between two vertices.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.
