Two circles of radius 1, passing through each other’s centres.... I can see where √1, √2, √3, √4, √5, √7, √8, √9, and √ 10 appear on the diagram. Help me find if √6 is hiding somewhere!

@DearAuntCrabby @morningmika @ColleenHenley You are exactly right!!! When he said he would not wear a mask, how many of his followers vowed not to wear a mask and how many thousands have been infected by these followers not wearing a mask?

@AnthonyMasonCBS Neat numbers for your son’s birthday. Your cohosts didn’t seem to pick up on the significance. My fifth grade teacher told us she turned 19 on Oct 19, 1919. I thought that was neat. Still do. Thanks for sharing. Happy Special Birthday to Nick Mason.

@aap03102 @MathsScot @scottishmaths @Mathematical_A @mathsjem @misterwootube @RachelRileyRR @UKMathsTrust I like it. An interesting extension: How would you construct this rectangle so that its side lengths are exactly 4 + sqrt(2) and 4 - sqrt(2) units long as stated?
