So lets ABCD are the sides of the square and AB=CD, AC=BD and the Angle ABC = 90 so therefore by making a diagonal we can use the SAS or SSS congruency for two triangles, so we can prove two triangles are equal and that is why the shape is square.

Which numbers are perfect squares? Check all that apply.

Andrew [12]

A perfect square is a number made by squaring a whole number.

Since

$1^2=1;$
$4^2=16;$
$10^2=100,$

numbers 1, 16, 100 are perfect squares. You cannot find such whole number n, that

$2=n^2;$
$18=n^2;$
$32=n^2;$
$44=n^2;$
$94=n^2,$

therefore, numbers 2, 18, 32, 44, 94 are not perfect squares.

Answer: 1, 16, 100.

Isolate x; you must get all the constants on one side of the equation and the variables on the other side. Use subtraction/addition to do this. Reply to me once you've done that if you still need help.
