What is the geometric mean of two numbers?

Back

Front

Calculate the geometric mean of 8√2 and √2.

Back

The geometric mean is 4√2.

Front

What is a tangent segment in geometry?

Back

A tangent segment is a line segment that touches a circle at exactly one point.

Front

If two segments are tangent to a circle, what can be said about their lengths?

Back

The lengths of the tangent segments drawn from a point outside the circle to the circle are equal.

Front

What does it mean for segments to be parallel?

Back

Two segments are parallel if they are in the same plane and do not intersect, no matter how far they are extended.

Front

Identify a segment that is parallel to segment EF.

Back

Segment NP is parallel to segment EF.

Front

What is the formula for finding the measure of an angle in a triangle?

Back

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

Front

If one angle in a triangle measures 49°, what is the measure of the missing angle if the other angle measures 82°?

Back

The missing angle measures 49°.

Front

What is the relationship between tangent segments and the radius of a circle?

Back

A tangent segment is perpendicular to the radius drawn to the point of tangency.

Front

How do you find the value of x in a geometric problem involving tangents?

Back

Use the properties of tangents and the Pythagorean theorem if necessary.
