Circle Angles & Segments 10-second questions

Front

What are chord angles in a circle?

Back

Chord angles are angles formed by two chords in a circle that intersect at a point inside the circle.

Front

What is the equation to find the value of x when given the lengths of two segments in a circle?

Back

The equation is x^2 = 4(4 + 5), where the segments are related to the circle's geometry.

Front

What is an example of a chord/chord angle?

Back

An example of a chord/chord angle is the angle formed by two chords that intersect inside the circle.

Front

What is an example of a tangent/secant angle?

Back

An example of a tangent/secant angle is the angle formed between a tangent line to the circle and a secant line that intersects the circle.

Front

What is the equation to find the value of x in a right triangle formed by a radius and a secant?

Back

The equation is x^2 + 4^2 = 12^2, which follows the Pythagorean theorem.

Front

What is the relationship between the angles formed by two intersecting chords?

Back

The measure of the angle formed by two intersecting chords is equal to half the sum of the measures of the arcs intercepted by the angle.

Front

How do you calculate the measure of an angle formed by a tangent and a chord?

Back

The measure of the angle formed by a tangent and a chord is equal to half the measure of the intercepted arc.

Front

What is the definition of a secant in relation to a circle?

Back

A secant is a line that intersects a circle at two points.

Front

What is the definition of a tangent in relation to a circle?

Back

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

Front

What is the relationship between the lengths of segments created by two intersecting chords?

Back

The products of the lengths of the segments of each chord are equal: if two chords intersect, then the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the other chord.
