With the Help of the Information Given in the Figure, Fill in the Boxes to Find Ab and Bc . - Geometry

With the help of the information given in the figure, fill in the boxes to find AB and BC .

AB = BC                    (Given)

∴∠ BAC = ∠ BCA =     
∴ AB = BC =    × AC
   × `sqrt8`
      × `2sqrt2`
= 2

Solution

AB = BC
∠ BAC = ∠ BCA =45˚

AB = BC = `1/sqrt2 × AC`

= `1/sqrt2 × 8 = 1/sqrt2 × sqrt(4×2)`

= `1/sqrt2 × 2sqrt2`
= 2
