2020 AIME I - Reflection Notes from H
Did: #8–15
Had trouble / wrong: #12, #15
Need Review / Unclear:
#12 – Don’t know LTE, but I was very close to solving this using the binomial theorem.
#15 – Wasn’t able to see the symmetry: the circumcircle of IBC (with the orthocenters) is a reflection of the circumcircle of ABC.
