Intersecting Chords Theorem
This is the idea (a, b, c and d are lengths):
And here it is with some actual values (measured only to whole numbers):
- 71 × 104 = 7384
- 50 × 148 = 7400
Very close! If we measured perfectly the results would be equal .
Why not try drawing one yourself, measure the lengths and see what you get?
Why is this true?
Because there are similar triangles!Lookingbelow:
- The angles θ are the same (see vertically opposite angles )
- The angles φ are the same (see inscribed angles )
The triangles may not be the same size, but they have the same angles ... so all lengths will be in proportion!
One triangle has the ratio a/c, and the other has the matching ratio d/b:
a × b = c × d

Background Tutorials
Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers..
What's the Subtraction Property of Equality?
Solving equations can be tough, especially if you've forgotten or have trouble understanding the tools at your disposal. One of those tools is the subtraction property of equality, and it lets you subtract the same number from both sides of an equation. Watch the video to see it in action!
Giving quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in which the data were gathered.
How Do You Find an Average?
What is the average temperature outside today? What is the average amount of time it takes you to do your homework? What is the average price for a gallon of gas? To figure out how to find the average to just about anything, check out this tutorial about averages!
Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.
What are Vertical Angles?
Vertical angles have a very special quality. They are always congruent to one another! Check out this tutorial to learn about and see how to identify vertical angles!
Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.

A secant is the name given to a line which extends through a circle cutting the circumference at two points. It occurs when two chords intersect outside of the circle. For two chords, AB and CD that extend and meet at point P outside of the circle. AP : PD ≡ CP : PB where AP = AB + BP and CP = CD + DP. Therefore (AB + BP) : PD ≡ (CD + DP) : PB.
