Module 6: Relationships in Triangles

Front

What is the Incenter of a triangle?

Back

The Incenter is the point where the angle bisectors of a triangle intersect. It is equidistant from all three sides of the triangle.

Front

What are the medians of a triangle?

Back

Medians are line segments that connect each vertex of the triangle to the midpoint of the opposite side.

Front

If BF = 10 in triangle ABC, what is AF if CF, BE, and AD are the medians?

Back

AF = 10.

Front

What is the Orthocenter of a triangle?

Back

The Orthocenter is the point where the altitudes of a triangle intersect.

Front

What segments intersect at the Incenter?

Back

The Incenter is the intersection of the angle bisectors of a triangle.

Front

What is the Circumcenter of a triangle?

Back

The Circumcenter is the point where the perpendicular bisectors of the sides of a triangle intersect.

Front

What is the Centroid of a triangle?

Back

The Centroid is the point where the three medians of a triangle intersect.

Front

How do you find the measure of an angle in a triangle?

Back

Use the properties of triangles, such as the sum of angles in a triangle equals 180 degrees.

Front

What is the relationship between the sides and angles of a triangle?

Back

In a triangle, the larger the angle, the longer the opposite side.

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.
