Question

, if ∠A = ∠C and AB = BC, then show that ∆ ≅∆ ABD CBE​

Answer 1

Answer:

Answer:=》AB= sqrt 36 cm=6cm

● Step-by-step explanation:

Given

Given BC = 9cm and BD=4cm CD=BC-B =5cm In Delta*A * B * C and Delta*A * B * D

• angle ABD= angle ABC

• angle ADB= angle BAC=right ar angle

• angle BAD= angle ACD(remaining) So Delta*A * B * C and Delta*A * B * D are similar

Hence

(AB)/(BC) = (BD)/(AB)

=》AB^ 2 =BD* BC=4*9=36

=》AB= sqrt 36 cm=6cm
