Intersecting Chords Practice

Front

What is the Intersecting Chords Theorem?

Back

The Intersecting Chords Theorem states that if two chords intersect inside a circle, the products of the lengths of the segments of each chord are equal.

Front

If two chords AB and CD intersect at point E, how can you express the relationship between the segments?

Back

If AE and EB are segments of chord AB, and CE and ED are segments of chord CD, then AE * EB = CE * ED.

Front

What is the formula to find the length of a chord in a circle?

Back

The length of a chord can be found using the formula: L = 2 * r * sin(θ/2), where r is the radius and θ is the angle subtended by the chord at the center.

Front

How do you find the value of x in intersecting chords problems?

Back

To find x, set up the equation based on the Intersecting Chords Theorem and solve for x.

Front

What is the significance of the point where two chords intersect?

Back

The point where two chords intersect divides each chord into two segments, which can be used to find unknown lengths using the Intersecting Chords Theorem.

Front

If chord AB is 10 units long and chord CD is 8 units long, what can be said about their segments if they intersect?

Back

The products of the segments of each chord will be equal, allowing for the calculation of unknown segment lengths.

Front

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

Back

The angles formed by intersecting chords are vertical angles and are equal to each other.

Front

How can you determine the length of a segment of a chord if you know the lengths of the other segments?

Back

Use the Intersecting Chords Theorem: if AE * EB = CE * ED, you can solve for the unknown segment.

Front

What is the first step in solving an intersecting chords problem?

Back

Identify the segments created by the intersecting chords and label them appropriately.

Front

If two chords intersect and one segment is 3 units and the other is 5 units, what is the product of the segments?

Back

The product of the segments is 3 * 5 = 15.
