3rd six week Exam

Front

If G is the centroid of triangle ABC and BE= 18. Find the length of BG.

Back

BG = 12 (The centroid divides each median in a 2:1 ratio.)

Front

Solve for x in a parallelogram where opposite angles are equal.

Back

x = 2 (In a parallelogram, opposite angles are equal.)

Front

Identify the figure that bisects an angle into two equal parts.

Back

Angle bisector (An angle bisector divides an angle into two equal angles.)

Front

In triangle ABC, which angle is the largest if the sides are a, b, and c?

Back

∠E (The largest angle is opposite the longest side.)

Front

Find BC if the triangle's sides are given as 4, 16, 12, and 24.

Back

BC = 24 (The longest side in the triangle.)

Front

What is the definition of a centroid in a triangle?

Back

The centroid is the point where the three medians of the triangle intersect.

Front

What is the property of the diagonals in a parallelogram?

Back

The diagonals bisect each other.

Front

What is the relationship between the angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.

Front

Define 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 definition of an angle bisector?

Back

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