Fall Semester Exam Review - Geometry

Front

If points A, B and C are collinear and B is between A and C, given AC = 27 and AB = 18, find BC.

Front

What is the formula for finding the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What are corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal.

Front

If two angles are alternate interior angles, what can be said about their measures?

Back

They are equal if the lines are parallel.

Front

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

Back

180 degrees.

Front

How do you find the measure of an exterior angle of a triangle?

Back

It is equal to the sum of the two opposite interior angles.

Front

What is the Pythagorean theorem?

Back

In a right triangle, $a^2 + b^2 = c^2$, where c is the hypotenuse.

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

Distance = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

Front

What is the definition of collinear points?

Back

Points that lie on the same straight line.

Front

What is the definition of a transversal?

Back

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