4.5 Warm Up: Intersecting Line Lengths

Front

What is the formula for finding the lengths of two intersecting chords in a circle?

Back

Part x Part = Part x Part

Front

What is the formula for finding the lengths of two intersecting secants?

Back

Outside x Whole = Outside x Whole

Front

What is the formula for finding the length of a tangent and a secant that intersect outside the circle?

Back

Tangent² = Outside x Whole

Front

If two chords intersect inside a circle, how do you find the lengths of the segments?

Back

Multiply the lengths of the segments of one chord and set it equal to the product of the segments of the other chord.

Front

What does 'Outside' refer to in the context of secants and tangents?

Back

The length of the segment of the secant or tangent that lies outside the circle.

Front

What does 'Whole' refer to in the context of secants?

Back

The total length of the secant from the point of intersection to the farthest point on the circle.

Front

How do you solve for 't' when two chords intersect in a circle?

Back

Set the products of the segments equal to each other and solve for 't'.

Front

What is the relationship between the lengths of intersecting chords in a circle?

Back

The products of the lengths of the segments of each chord are equal.

Front

If a secant and a tangent intersect at a point outside the circle, what is the relationship between their lengths?

Back

The square of the length of the tangent equals the product of the lengths of the secant's outside part and the whole secant.

Front

What is the significance of rounding in geometric problems?

Back

Rounding is important for providing a practical answer, especially when dealing with measurements.
