Geometry: Ch5-Relationships in Triangles

Front

Which line segment is an angle bisector?

Back

AC is the angle bisector, dividing the angle into two equal parts.

Front

The centroid is the point of concurrency of the 3 ____ of a triangle.

Back

Medians.

Front

If GC is 11, what is AG?

Back

AG is also 11, as AG and GC are equal segments.

Front

If DL = 24, then DG = ?

Back

DG = 8, as it is a segment of DL.

Front

If CG = 4x + 3 and AG = 3x + 4, what is BG?

Back

BG = 7, found by solving the equations.

Front

What is the definition of a median in a triangle?

Back

A median is a line segment joining a vertex to the midpoint of the opposite side.

Front

What is the circumcenter of a triangle?

Back

The circumcenter is the point where the perpendicular bisectors of the sides intersect.

Front

How do you find the length of a segment using the midpoint theorem?

Back

The length of a segment can be found by using the coordinates of the endpoints and applying the midpoint formula.

Front

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

Back

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

Front

What is an angle bisector?

Back

An angle bisector is a ray that divides an angle into two equal angles.
