Geometry Unit 5 Vocab and Midsegment Theorem

Front

What is the definition of an altitude in geometry?

Back

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

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 relationship between a perpendicular bisector and the midpoint of a segment?

Back

A perpendicular bisector is perpendicular to and always passes through the midpoint of a segment.

How do you find the value of y if a segment labeled 'x+4' is a midsegment?

Back

You would use the properties of midsegments in triangles, which state that the midsegment is parallel to the base and half its length.
