10. InWC is the midpoint of AB and D is the midpoint of AC.Prove that AD = -AB. Explain by drawing the figure.from any one |
|
Answer» Here's the solution: AC = CB (as C is the mid-point of line segment AB) Add AC to both sides, we get AC + AC = AC + CB ( Axiom 2: If equals are added to equals, then the wholes are equal) So, 2 AC = AB (as AC+CB = AB) AC = AB/2 ........ (1) Next, AD = DC (as D is the mid-point of AC) Add AD to both sides, we get AD + AD = AD + DC (Axiom 2; same as above) 2 AD = AC (as AD + DC = AC) Therefore, AD = AC/2 ......... (2) Substituting value of AC from (1) in (2), we get AD = AB/2÷ 2 AD = AB/2 x 1/2 AD = 1/4 AB |
