Median & Altitude (2022-2023)

Front

What is the definition of an altitude in a triangle?

Back

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

Front

What is the definition of a median in a triangle?

Back

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

Front

If the altitude of a triangle is 10 cm, what does this mean?

Back

It means that the perpendicular distance from the vertex to the opposite side is 10 cm.

What is the relationship between the altitude and the area of a triangle?

Back

Front

In triangle ABC, if AD is the altitude from A to BC, what can be said about angles ADB and ADC?

Back

Angles ADB and ADC are right angles (90°) because AD is perpendicular to BC.

Front

What is the significance of the median in a triangle?

Back

The median divides the triangle into two smaller triangles of equal area.

Front

What is the difference between an altitude and a perpendicular bisector?

Back

An altitude is drawn from a vertex to the opposite side, while a perpendicular bisector is drawn from the midpoint of a side and is perpendicular to that side.
