When discussing theorem 10.10, it was mentioned that y=98 and x=112. This is impossible based on theorem10.10. y must be equal to 112 and x must be equal to 98. also, the lady mentioned that in quadrilaterals, consecutive angles are supplementary, but that is only true of parallelograms.
Nice catch. Thanks for pointing out these errors. Did you comment on the original video? If you have time, it would help future viewers.
