Question

i require help in solving this

Answer 1

Answer:

Step-by-step explanation

• since it is a square which means all 4 side

i.e. AB=BC=CD=DA_____(1)

• given that equilateral triangle

∴ DE=CD=CE_______(2)

• ∠BCD+∠ECD=90°+60°

                          ∠BCE  =150°

Similarly we have∠ADE = 150°_____(3)

In Triangle ADE and Triangle BCE

AD=BC   [proved in equation(1)]

DE=CE [proved in equation(2)]

∠BCE=∠ADE [proved in equation ____(3)

∴Triangle ADE ≅Triangle BCE (BY SAS Congurency)
