Triangle Calculator
Kuchotsa aliyense triangle kuchokera zigawo ndi ang'onoang'ono - nyanja, perimeter ndi zosakwanira mfundo.
Ikani malingana ndi 3 (pafupifupi m'mbali imodzi). Malingana a, b, c ndi osiyana siyana A, B, C.
Kulemba mu maganizo atatu kuti akwaniritse.

A triangle calculator solves a triangle from the values you know (three sides, two sides and an angle, or two angles and a side) using the law of sines and law of cosines. It returns every missing side and angle plus the area and perimeter. Enter the values you have and leave the rest blank.
You need any three values that include at least one side. From that it picks the right theorem: the law of cosines recovers an angle from three sides or a third side from two sides and their included angle, while the law of sines pairs a known side with its opposite angle to find the rest. Because a triangle’s angles always sum to 180°, once two angles are known the third follows immediately. It then reports the perimeter and the area.
For a worked example, entering the three sides 3, 4 and 5 identifies a right triangle: the angle opposite the longest side is exactly 90°, the other two are about 36.87° and 53.13°, the perimeter is 12 and the area is ½·3·4 = 6. Give it two sides and the included angle instead — say 5, 7 and 40° — and it uses the law of cosines to find the third side. It is used in geometry and trigonometry homework, surveying, construction layout and any job that needs the missing measurements of a triangle.
Mafunso ofunsidwa nthawi zambiri
Kodi ndiyenera kudziwa chiyani kuti ndithe kufotokoza mfundo za triangle?
Mtengo uliwonse wa masentimita atatu womwe umaphatikizapo at least mbali imodzi: masentimita atatu (SSS), masentimita awiri ndi gawo lophatikizidwa (SAS), masentimita awiri ndi gawo (ASA/AAS), kapena masentimita awiri ndi gawo lophatikizidwa (SSA).
Kodi ndi mmene nyanja imawerengedwa?
Kuchokera pa zigawo zitatu izo amagwiritsa ntchito Heron's formula; ndi zigawo ziwiri ndi kuphatikizidwa angle izo amagwiritsa ntchito ½ · a · b · sin (C).
Kodi ndingatani kuti ndikwaniritse 3-4-5 triangle?
Kulemba mbali zitatu monga 3, 4 ndi 5 ndi kuchotsa nyanja zosaoneka. The calculator amatsimikizira kuti ndi nyanja yoyera ndi 90 ° nyanja yotsutsana ndi mbali ya m'lifupi 5, nyanja za pafupifupi 36.87 ° ndi 53.13 °, nyanja 6 ndi nyanja 12.
Kodi pali kusiyana kotani pakati pa malamulo a sines ndi malamulo a cosines?
M’malamulo a kosinesi timapeza kuti maziko atatu onse amagwirizana ndi m’mbali imodzi. M’malamulo a sines timapeza kuti maziko atatu onse amagwirizana ndi m’mbali imodzi. M’malamulo a cosines timapeza kuti maziko atatu onse amagwirizana ndi m’mbali imodzi.
N’chifukwa chiyani SSA nthawi zina amapereka awiri triangles zotheka?
Ndi maziko awiri ndi kutalika kopanda malire (kapena kachilombo), maziko angafike pamalo awiri osiyana, kotero ma triangles awiri oyenera angagwiritsidwe ntchito pazolemba zofanana. Kalkuluta imasonyeza izi pamene izi zikuchitika.
Kodi anganene ine ngati mfundo zanga si zogwirizana ndi triangle?
Ngati maziko a triangle kuwononga chisamaliro (chigawo chimodzi m'mbali m'litali kuposa ena awiri kuphatikizidwa) kapena ang'onoang'ono sakhoza kuwonjezera kuti 180 °, calculator akudziwitsa kuti palibe monga triangle ali paliponse m'malo kubwezera zotsatira.
Zimenezi ndi zowerengera zokhudzana ndi malangizo amtundu uliwonse, si zokhudzana ndi ndalama, zamoyo kapena zokhudzana ndi ndalama.
