What is a midsegment in a triangle?

Back

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

Front

If QR is a midsegment of triangle BCD, how do you find the value of x?

Back

To find the value of x, use the property that the midsegment is half the length of the side it is parallel to.

Back

Segment DE is a midsegment of triangle ABC.

Front

What is the relationship between a median and a triangle?

Back

If QR is a midsegment of triangle WUV, what is the length of segment QR if the side it is parallel to is 16?

Back

The length of segment QR is 8, as it is half the length of the side it is parallel to.

What is the circumcenter of a triangle?

Back

The circumcenter is the point where the perpendicular bisectors of the sides of a triangle intersect, and it is equidistant from all three vertices.

Front

If point P is the circumcenter, which segment is equal to PB?

Back

Segment PC is equal to PB, as they are both radii of the circumcircle.

Front

What is the difference between a median and an altitude in a triangle?

Back

A median connects a vertex to the midpoint of the opposite side, while an altitude is a perpendicular segment from a vertex to the line containing the opposite side.

Front

How do you identify a midsegment in a triangle?

Back

A midsegment can be identified as a segment connecting the midpoints of two sides of the triangle.
