Okay, given it's an esoscelese trapezoid, so since it's a acosceles trapezoid, i spelled that wrong, since it's an esosalese trapezoid, we know that, we know that these two are parallel, so that's correct.

B, d is perpendicular to ac? no, it's not perpendicular.
00:48
Those are not perpendicular.
00:49
That's not true.
00:50
B -a is congruent to c -d so that is true because it is a soceles so if it's aosceles, my base angles are congruent so a -b -c angle a -b -c is going to be congruent to angle a -d -c and these two are also going to be congruent so angle b -a -c is going to be congruent to i wrote this one backwards.

I apologize.
01:35
That shouldn't have been to a either.
01:38
That should be b, c, d.
01:43
Sorry.
01:44
That's this angle...
