Stretch out your arms,but don't damage.
Only in squares and rectangles. In a rhombus, the consecutive angle is supplementary (sums to 180 degrees).
4 squares have 16 angles
There is no pair of perfect squares that sums to 21. And the question is pointless if it is not about perfect squares because in that case there are infinitely many answers.There is no pair of perfect squares that sums to 21.

A square has 4 angles, so ten squares have 10*4 = 40 angles.
A square has 4 interior right angles; 2 squares therefore have 8 angles.
When comparing the sums of squares of normal variates.
360 degrees.
For an array of numbers, it is the square of the sums divided by the sum of the squares.
Squares have 4 rights angles but a rhombus may or may not have 4 right angles.
Yes, by definition. All squares have 4 right angles and 4 sides of equal length.
