Geometry Midterm

Front

Define non-collinear points.

Back

Non-collinear points are points that do not all lie on the same straight line.

Front

What is a plane in geometry?

Back

A plane is a flat, two-dimensional surface that extends infinitely in all directions.

Front

How is a plane named?

Back

A plane can be named by any three non-collinear points on the plane or by a single uppercase script letter.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

Solve for x: 2x + 4 = 16.

Back

x = 6.

Front

Find the length of KL if the distance between points K(2,3) and L(2,9) is needed.

Back

KL = 6.

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 Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
