The video presents a geometry puzzle involving a triangle and a circle. The triangle is a 30-60-90 triangle with a height of 2, and the circle is a unit circle tangent to two of the triangle's sides. The circle and the hypotenuse of the triangle intersect, forming a chord. The task is to find the length of this chord.
The video explains a method to solve this puzzle using the properties of circles and the Pythagorean theorem. The video then demonstrates how to find the length of the chord by first determining the length of a segment that is perpendicular to the midpoint of the chord. This segment is then used to find the length of the chord by using the Pythagorean theorem. The video also explains how to use the properties of 30-60-90 triangles to simplify the calculation.
The video concludes by showing the final calculation, which results in the length of the chord being the square root of 2 times the cube root of 3. The video thanks the viewer for watching and invites them to like, comment, and subscribe to the channel.
