Question

can someone answer this fast
find the angle
how is it congrurent
and how is it a square

Answer 1

Answer:

In ΔABC & ΔFBE

∠B=∠B         (COMMON)                                            

∠A=∠F=90°

BA=BE          (ASA)

∴ΔABC≅ΔFBE

∴∠ABC=∠FBE                (CPCT)

To prove ABFG is a square, we have to prove that ABFG is a parallelogram, AB = BF = FG = AG, and one of its interior angles is 90°. are equal to each other only when the two lines are parallel. ... One of the interior angles of quadrilateral ABFG is a right angle.
