Question

आकृति में दी गई जानकारी के आधारपर AB और BC ज्ञात करने के लिए नीचे दी गई कृति पूर्ण कीजिए।

AB = BC .........${\displaystyle \square }$

∴ ∠BAC = ${\displaystyle \square }$

∴ AB = BC = ${\displaystyle \square }$ × AC

= ${\displaystyle \square }$ × ${\displaystyle \sqrt{8}}$

= ${\displaystyle \square }$ × ${\displaystyle 2\sqrt{2}}$

= ${\displaystyle \square }$

 

Answer 1

AB = BC .........(दिया है)

∴ ∠BAC = ${\displaystyle \underline{{45}^{\circ }}}$

∴ AB = BC = ${\displaystyle \underline{\frac{1}{\sqrt{2}}}}$ × AC

= ${\displaystyle \underline{\frac{1}{\sqrt{2}}}}$ × ${\displaystyle \sqrt{8}}$

= ${\displaystyle \underline{\frac{1}{\sqrt{2}}}}$ × ${\displaystyle 2\sqrt{2}}$

= 2
