How should we formulate angle geometry constraints in Mathematica to help the solving system work more efficiently and speed up the solution process?
Quadrilateral $ABCE$ is a parallelogram. Point $D$ lies on segment $AE$. The diagonals of quadrilateral $ABCD$ intersect at point P. If $△しろさんかくABP∼△しろさんかくCBD$ and $AB<BC,ドル find the ratio $\frac{AB}{BC}$.
The ...

How to improve the symbolic computation speed for plane geometry with multiple constraint conditions?
This is the simple geometry problem I want to solve:
In triangle ABC with side lengths a, b, c respectively, there is a point D on side AB, where AD = d. Find the length of CD.
When solving this ...
