Question from Heidemarie, a student: The vertices of an equilateral triangle with side length of 10 sqrt 3 cm lie on a circle. Find the side length of the regular hexagon whose vertices lie on the same circle. |
Hi,
$PR$ is perpendicular to $QS.$
What is the measure of the angle $SPQ?$
What is the measure of the angle $QSP?$
The result follows for knowing that in a "30, 60 90" triangle the ratio of the side lengths is $1:2:\sqrt{3}.$
