ABCD is a square and ABE is an equilateral triangle outside the square then

Draw a Delta ABC . 1. Bisect angleB and name the point of intersection of AC and the angle bisecto as D. 2. Mesure the sides. AB= square cm , BC = square cm, AD = square cm, DC = square cm 3. Find rations (AB)/(BC) and (AD)/(DC) . 4. You will find that both the rations are almost equal. 5. Bisect remaining angles of the triangle and find the ration as above. Verify that the ratios are equal.

The length of a diagonal of a square is sqrt2 times its side.

Let's calculate mentally. 9 xx 98 = 9 xx (100-2) = square xx square - square xx square = square
