a regular octagon is formed by cutting congruent isoceles traingles from the corners of a square,if the square has side length 1 the side length of the octagon is?
kvpy ques
ABCD is a square of side length 1.
isosceles triangles are cut from the corners.
let AP = x , in the right angled triangle PAW;
WV = 1- (x+x) = 1-2x
since PQRSTUVW is a regular octagon.
therefore PW = WV
thus side length of octagon is units
hope this helps you.
cheers!!
