برای پیدا کردن زاویه بین عقربه ساعت شمار و دقیقه شمار از فرمول زیر استفاده میشود.اگر پس از محاسبه زاویه از 180 درجه بیشتر شد عدد حاصل رو از 360 کم کنید تا زاویه به دست باید.
زاویه بین دو عقربه برابر است با:
( 30*ساعت -5/5 *دقیقه)
مثلا برای ساعت 12:20 عدد 5/5 را در 20 و30را 12 ضرب کنید. و حاصل ضرب ها را از هم کم کنید.پاسخ زاویه بین عقربه ها میشه
توجه:فرمول را از سمت چپ بخوانید
