Answers
Answer:
this is the prove of pythagoras theorem
Answer:
GIVEN: IN A RIGHT ANGLED TRIANGLE , THE SQUARE OF THE HYPOTENUSE IS EQUAL TO THE SUM OF SQUARES OF THE OTHER TWO SIDES.
TO PROOF :
CONSTRUCTION : DRAW BD⊥AC
PROOF :
IN ΔADB AND ΔABC
∠ADB = ∠ABC ( EACH 90° )
∠A = ∠A ( COMMON )
ΔADB ~ ΔABC ( BY AA SIMILARITY RULE )
( C.P.S.T. )
. . . (1)
IN ΔBDC AND ΔABC
∠CDB = ∠ABC ( EACH 90° )
∠C = ∠C ( COMMON )
ΔBDC ~ ΔABC ( BY AA SIMILARITY RULE )
( C.P.S.T. )
. . . (2)
ADDING (1) AND (2)
