in the given figure AB is parallel to DE and ∠ABC=∠DEF. Prove that BC is parallel to EF​

Answer 1

Answer:

Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds composed of atoms, molecules and ions: .

Answer 2

Step-by-step explanation:

Area of ADE=10

ABC and CDE are similar triangles

Since AD=DB

AD =1/2 DB

therefore all sides of triangle ADE are 1/2 of the respective sides of triangle ABC

Let the altitude of triangle ABC =h

Then the altitude of triangle ADE =h/2

Area of triangle ABC =1/2 BC*h =40

Area of triangle ADE=1/2(BC/2*H/2) = 1/2(BC*h/4)

so area of triangle ADE=1/4 area of ABC =10
