Geometry: Semester 1 Review

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

Which lengths cannot represent the sides of a triangle? 3, 10, 8; 2, 5, 8; 7, 5, 4; 5, 2, 4?

Back

2, 5, 8 cannot represent the sides of a triangle.

Front

What are complementary angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

If angle A is 70 degrees, what is the measure of its complementary angle?

Back

20 degrees.

Front

If angle B is 110 degrees, what is the measure of its supplementary angle?

Back

70 degrees.

Front

What is the measure of an angle if it is vertical to a 36-degree angle?

Back

36 degrees.

Front

How do you solve for x in the equation x + 5 = 10?

Back

x = 5.

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 a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.
