Front

What are Perpendicular Bisectors in a triangle?

Back

Perpendicular bisectors are lines that divide a side of a triangle into two equal parts at a right angle.

Front

Can side lengths of 8 in., 9 in., and 17 in. form a triangle?

Back

No, these lengths do not satisfy the triangle inequality theorem.

Front

How do you find the length of a missing side in a triangle?

Back

Use the Pythagorean theorem or the triangle inequality theorem, depending on the triangle type.

Front

Back

The angle opposite the shortest side is 37°.

Front

What is the length of side AB if the options are 6, 11, 17, and 68?

Back

The length of side AB is 17.

Front

What is the Triangle Inequality Theorem?

Back

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

Front

What is a Median in a triangle?

Back

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

Front

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

Back

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

Front

What is the definition of an Altitude in a triangle?

Back

An altitude is a perpendicular segment from a vertex to the line containing the opposite side.

Front

What is a Midsegment in a triangle?

Back

A midsegment connects the midpoints of two sides of a triangle and is parallel to the third side.
