Geometry Problem 1531: Discover How to Calculate the Length of a Chord in a Circle with Diameter Intersection and an Angle between the Diameter and Chord - A High School Challenge

Consider a circle with center O. A chord AB intersects the diameter CE at point D, such that CD = 1, DO = 2, and angle BDE measures 30 degrees. Find the length of AD.

Thematic Poem: Chasing the Chord: A Pythagorean Tale of Discovery Within a Circle

Within a circle's curved embrace,
A chord cuts through with angled grace,
Where diameter and chord do meet,
A Pythagorean tale to complete.

A challenge set to find the length,
Of this chord, with geometry's strength,
By applying the theorem's might,
And revealing its hidden insight.

"Discover!" cries the eager mind,
To unravel this puzzle designed,
To hone its skill with every try,

With steps and rules to guide the way,
The path to solve now on display,
A journey that the curious crave,
To find the chord they aim to save.

And when at last the chord is found,
A joyous victory does resound,
For knowledge gained is a treasure bright,
And with it, wisdom takes its flight.
