Special Segments of Triangles

Front

What is an altitude in a triangle?

Back

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

Front

What is a median in a triangle?

Back

A median is a segment from a vertex of a triangle to the midpoint of the opposite side.

Front

What is a perpendicular bisector?

Back

A perpendicular bisector is a segment that divides another segment into two equal parts at a right angle.

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

How do you find the measure of an angle using an altitude?

Back

Use the properties of right triangles formed by the altitude to apply trigonometric ratios or the Pythagorean theorem.

What is the relationship between the median and the centroid of a triangle?

Back

The centroid is the point where the three medians of a triangle intersect, and it divides each median into a ratio of 2:1.

How can you identify an angle bisector in a triangle?

Back

An angle bisector can be identified as the segment that splits the angle into two equal parts and can be measured using angle measures.
