B)FAB=40 degree
C)ACD=50 degree
D)BAD=90 degree​

Answer 1

Answer:

where is the figure

plz att h the photo also

Answer 2

Answer:

In △ABD & △BDC, we have

∠ADB=∠BDC [∵∠D is bisected ]

∠ABD=∠DBC [∵∠B is bisected ]

BD=BD (common)

∴△ABD≅△BDC (By ASA rule)

⟹AD=DC & BC=AB (By CPCT) -------(1)

AB=CD and BC=AD (ABCD is a rectangle) -------(2)

From (1) and (2)

∴AB=BC=CD=DA and ∠A=∠B=∠C=∠D=90

∘

(ABCD is a rectangle)

⟹ ABCD is a square
