M2T1 Part 2 Review

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

Can a triangle be formed with side lengths 15 in., 12 in., and 2 in.?

Back

No, because 15 + 12 is not greater than 2.

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

If two angles of a triangle measure 56° and 37°, what is the measure of the third angle?

Back

87°.

Front

Define a rhombus.

Back

A rhombus is a quadrilateral with two sets of parallel sides and all four sides of equal length.

Front

What are the properties of opposite angles in a parallelogram?

Back

The opposite angles of a parallelogram are congruent.

Front

What is the relationship between the angles in a triangle?

Back

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

Front

If angle ABC = 76°, what is angle CDA if they are alternate interior angles?

Back

Angle CDA = 104°.

Front

What is a complementary angle?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is a supplementary angle?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.
