  • Square \(\;(SQ)\:\) is a quadrilateral with four parallel edges.
  • Interior angles are 90°.
  • Exterior angles are 90°.
  • 2 diagonals
  • 4 edges
  • 4 vertexs 

Edge formula

\(a= \sqrt A \)

Where:

\(a\) = edge

\(A\) = area

Perimeter formula

\(P= 4a \)

Where:

\(P\) = perimeter

\(a\) = edge

Area formula

\(A= a^2 \)

Where:

\(A\) = area

\(a\) = edge
