Step-by-step explanation:
It is given that x=y and AB=CB
By considering the △ABE
We know that
Exterior ∠AEB=∠EBA+∠BAE
By substituting ∠AEB as y we get
y=∠EBA+∠BAE
By considering the △BCD
We know that
x=∠CBA+∠BCD
It is given that x=y
So we can write it as
∠CBA+∠BCD=∠EBA+∠BAE
On further calculation, we can write it as
∠BCD=∠BAE
Based on both △BCD and △BAE
We know that B is the common point
It is given that AB=BC
It is proved that ∠BCD=∠BAE
Therefore, by ASA congruence criterion we get
△BCD≅△BAE
We know that the corresponding sides of congruent triangles are equal
Therefore, it is proved that AE=CD

Step-by-step explanation:
Forest conservation is the need of the hour.
They are also the source of rubber, gum and some medicinal products. Forests constitute the natural habitat for a large number of animals. In nature also, forests help in keeping the climate of an area cool, they absorb rain water and helps in prevention of floods.
