Muchidzidzo chePimanyika (geometry), skweya (square) chiumbwa chine mativi mana ose akaenzana negonya ina dzose dzakaenzana. Skweya riri mumupanda wegonyaina.

Pimamuganhu neNharaunda

Pimamuganhu yeskweya rine mativi akareba nhambwe K inowanikwa netsazaniso inoti:

Pimamuganhu, P = 4.K,

uye Nharaunda yeSkweya inowanikwa netsazaniso inoti:

Nharaunda, A = K²

Zvifaniro zveSkweya

Skweya iri mumupanda wegonyaina tsazamativi neruramamakonyo, saka zvinoreva kuti ine zvose zvifaniro (properties) zviumbwa zviviri izvi; sokuti:

• Guramakonya mbiri dzinochekana negonya re 90^o uye dzinochekana kuita zvikamu zviviri zvakaenzana.
• Guramakonya dzeSkweya dzinocheka makonya muzvikamu zviviri zvakaenzana.
• Mativi akatarisana eSkweya akaenzana uye akati sambamba.
• Guramakonya mbiri dzeSkweya dzakaenzana
• Makonya ose ari mana eSkweya akaenza ari 90^o
