idle wedge
#

i mean i know angle DST is x

#

and DTSF is a parallelogram

warped wing
#

TDS is 180-2x

#

There is alternate segment theorem in it

idle wedge
#

i don’t even know that theorem 😭

#

i need to learn circle theroems again

#

but what angles r the same then

short chasm
#

Do some angle chasing

#

Then

#

If things like alternate angles are equal/co interior angles add to 180 stuff that like are true they must be parallel

Search up on Google you will get ranges of examples by which you can understand

you only need it to say DST = DFS then you can do it without that theorem from there
