Can anyone show how to rotate this..........?

well for rotation u use a tracing paper plat the points on the paper and then place ur pencil on the the point (0,0) as given
rotate the tracing paper 9o clockwise and plot the points from the tracing paper on the grid and draw the triangle

How......................??

i will show u
u will expand it
a^1/2 * a^1/2 = a^1/2 + 1/2 = 1/2 +1/2 = 1 so it is a^1 = a
1 a^1/2 *b^ 1/2 = a^1/2 b^1/2
2 -b^1/2 + a^1/2 = a^1/2 - b^1/2 so u cancel these two that i numbered 1 and 2
b^1/2 * -b^1/2 = - b
so it is a -b

hope u got it
