Question

E & F are the mid-point of non-parrallel sides AD and BC of the trapezium ABCD. Prove that:-
I) EF || AB
II) EF = ½ (AB+CD)​

Answer 1

Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart.

Answer 2

Step-by-step explanation:

I} . EF ᴀʀᴇ ᴛʜᴇ ᴍɪᴅ ᴘᴏɪɴᴛ

AB ɪs ᴛʜᴇ ɴᴏᴛʜɪɴɢ ʙᴜᴛ ɪɴ ᴛʜᴇ ᴍɪᴅ ᴘᴏɪɴᴛᴇ ᴄᴀɴ ᴛᴀᴋᴇ ɪᴛ

AC = EF ..

II }. EF = ½ ( AB + CD)

EF = ½ x ½ = ¹/⁴⁴

= ¹/⁴⁴ + ¹/⁴⁴

= 207/36
