#

what's available in the Type of Statement dropdown box?

#

you can apply one of the triangle congruency rules given the information you have here

what have you tried

#

?

#

well from here congruency is immediate by applying one of the rules

#

if that's a valid entry in the Reason column

#

If you see geometry,ABC ≈BDA

#

E is intersection of the two triangles

#

And The segments ABE is other triangle

#

If you draw height h and aplic the sin reason.

#

You can prove it

What are X,Y and W

small mauve Dec 21, 2025, 7:33 PM

#

That’s just the format

#

There’s no sin, cos, in the reason box

#

I also didn’t learn that yet 😭
