What is the midsegment of a triangle?

Back

The midsegment of a triangle is a segment that connects the midpoints of two sides of the triangle. It is parallel to the third side and its length is half the length of that side.

Front

How do you find the value of x in the equation of a midsegment?

Back

To find the value of x in the equation of a midsegment, set the midsegment expression equal to the known length and solve for x.

Front

What is the Centroid Theorem?

Back

The Centroid Theorem states that the centroid of a triangle is located 2/3 of the distance from each vertex to the midpoint of the opposite side.

Front

If VT = 5, how long is VP according to the Centroid Theorem?

Back

VP = 10, because the centroid divides the median in a 2:1 ratio.

Front

What is a median in a triangle?

Back

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

Front

Which segment represents a median in a triangle?

Back

Segment BZ represents a median if it connects vertex B to the midpoint of side AC.

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

Which segment represents an altitude in a triangle?

Back

Segment BX represents an altitude if it is perpendicular to side AC from vertex B.

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

How can you identify a perpendicular bisector in a triangle?

Back

A perpendicular bisector can be identified as the segment that is perpendicular to a side of the triangle and passes through its midpoint.
