Geometry Semester 1 Review

Front

Do the following side lengths form a triangle? 5, 6, 9

Back

Yes, the side lengths satisfy the triangle inequality theorem.

Front

Angles a and c are...

Back

Corresponding angles are angles that are in the same position on different parallel lines.

Front

What is a regular polygon?

Back

A regular polygon is a polygon with all sides and angles congruent.

Front

What is the converse to this statement: 'If it is night, then it is dark outside'?

Back

The converse is: 'If it is dark outside, then it is night.'

Front

Name the postulate that makes the triangles congruent: SSS, SAS, ASA, Not Possible

Back

SSS (Side-Side-Side) postulate states that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

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

Define complementary angles.

Back

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

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 transversal in geometry?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two lines.
