In the following figure which of the following statements is true?
A. AB = BD
B. AC = CD
C. BC + CD
D. AD < Cd
Answer: Option B
Solution(By Examveda Team)
In Triangle ABD,∠BAD + ∠B + 90° = 180° or, ∠BAD + ∠B = 90° - - - - - - - (1) Now, in Triangle ABC, ∠ACB + ∠B + ∠A = 180° ∠ACB + ∠B = 180° - 90° ∠ACB = 90° - ∠B - - - - - (2) From (1) and (2), ∠BAD = ∠ACB So, AC = CDThis Question Belongs to Arithmetic Ability >> Triangles
In equation 1 --- angle BAD + angle B = 90
cannot be true unless angle BAD = 0
since angle B itself is 90
Can't agree..
can't agree
i agreed it well explaination
In the figure angle B is 90° then how can u say that BAD+B+90=180
good solution explained by Sannyasi. but the explanation provided by examveda is complete crap..
In Triangle ABD,
∠B=90,∠A=30+30=60degre
then ∠D=30degre
now Consider Triangle ACD
∠D=30,∠DAC=30
These two side is Opposite of two equal angle So, AC = CD.
Not agree could u explain further
I don't understand. Can explain more clearly please? Thank you
i dont agree
