What is the definition of an altitude in a triangle?

Back

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

Front

What is the relationship between the lengths of the sides of a triangle?

Back

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

Front

If two sides of a triangle measure 13 and 18, what is the range of possible measures for the third side?

Back

5 < s < 31

Front

What is a midsegment in a triangle?

Back

A midsegment is a line segment that connects the midpoints of two sides of a triangle.

Front

How long is the midsegment if one side of the triangle is 20?

Back

10

Front

What is the definition of a median in a triangle?

Back

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

Front

Which midsegment connects side DF to side DE?

Back

Front

If two sides of a triangle measure 20 and 8, what is the range of possible measures for the third side?

Back

12 < s < 28

Front

What is the definition of a perpendicular bisector in a triangle?

Back

A perpendicular bisector is a line that divides a side of a triangle into two equal parts at a right angle.

Front

What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that for any triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
