Question from Tabatha, a student:

The diagonals of a rectangle are 8 units long and intersect at a 60 degree angle. Find the dimensions of the rectangle.

Hi Tabatha,

I can get you started.


By the symmetry of the rectangle |AB| = |BC| so triangle ABC is an isosceles triangle. The measure of angle ABC is 60o. What are the measures of angles BCA and CAB? What is the length of CA?
