This post contains the answers to this week's Sunday Afternoon Maths and some extension problems based around the originals.
Guess the Diagonal
CG is equal to AF as they are both diagonals in a rectangle.
AF is a radius of the triangle, so AF = 10.
Therefore CG = 10.
AF is a radius of the triangle, so AF = 10.
Therefore CG = 10.
Extension
Calculate the lengths of CI and CJ.
Calculate the length of HG.
