What is the definition of a midsegment in a triangle?

Back

A midsegment is a line segment that connects the midpoints of two sides of a triangle, and it is parallel to the third side.

Front

How do you calculate the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of all three sides.

Front

If a line segment is a median of a triangle, what does it do?

Back

A median of a triangle connects a vertex to the midpoint of the opposite side, dividing the triangle into two smaller triangles of equal area.

Front

What is the triangle inequality theorem?

Back

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

In triangle ABC, if AB = 10 inches and BC = 17 inches, what is the range for the length of side AC?

Back

The length of side AC must be greater than |AB - BC| and less than (AB + BC), so it must be between 7 inches and 27 inches.

Front

What is the relationship between angles in a triangle?

Back

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

Front

How can you determine if two angles are complementary?

Back

Two angles are complementary if the sum of their measures equals 90 degrees.

Front

What is the formula for finding the length of a median in a triangle?

Back

Front

What is the definition of an angle bisector?

Back

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

Front

How do you find the value of x in an equation?

Back

To find the value of x, isolate x on one side of the equation using algebraic operations.
