Hence they are similar
#2
- <A=<H
- And ratio of sides are same
Hence both triangles are similar by SAS property
#3

It is less because 8(2/8) would equal 2
For this case we must find an expression equivalent to:
By definition of power properties we have to meet:

So, rewriting the expression we have:
