Unit 5 Test Review

Front

What is the largest angle in a triangle?

Back

The largest angle in a triangle is opposite the longest side.

Front

What is a parallel segment?

Back

Parallel segments are line segments that never intersect and are always the same distance apart.

Front

If QT < ST, what can be inferred about the lengths of QT and ST?

Back

QT is shorter than ST.

Front

How do you find the length of a segment in a triangle?

Back

Use the triangle inequality theorem or given measurements.

Front

Can a triangle be formed with side lengths 24, 9, and 30?

Back

Yes, because the sum of the lengths of any two sides is greater than the length of the third side.

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.

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices.

Front

What are the types of triangles based on side lengths?

Back

Scalene (no equal sides), Isosceles (two equal sides), Equilateral (all sides equal).

Front

What is the sum of the interior angles of a triangle?

Back

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

Front

What is the definition of a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.
