Triangle Calculator
Solve chero triangle kubva kumativi uye mativi - nzvimbo, perimeter uye kushaya zviyero.
Ingonyora chero 3 mavara (kana kuti imwe chete). Mativi a, b, c ndiwo mativi akaenzana eA, B, C.
Chivamisa mavara matatu kuti ugadzirise.

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.
Zvimwe zvinobvunzwa zvakanyanya
Chii chandinofanira kuziva kuti ndigadzirise nyaya yetriangle?
Any three values that include at least one side: three sides (SSS), two sides and the included angle (SAS), two angles and a side (ASA/AAS), or two sides and a non-included angle (SSA).
Sei nzvimbo inofungidzirwa?
Kubva kumativi matatu anoshandisa Heron’s formula; nematanhatu mativi uye neanosanganisira angle anoshandisa ½·a·b·sin(C). Vaviri ava vanopawo imwe cheteyo mhinduro yetriangle.
Maitiro ekubvisa 3-4-5 triangle?
Kunyora matatu mativi se 3, 4 uye 5 uye kugara angle vakasununguka. The calculator anobvuma kuti ari a right triangle ne 90 ° angle zvakananga kumusoro kwechiuno chekumusoro 5, angles pamusoro 36.87 ° uye 53.13 °, nzvimbo 6 uye perimeter 12.
Chii chinonzi chiyero chekuenzanisa pakati pechiyero chekuenzanisa uye chiyero chekuenzanisa?
Mutemo wecosines unobatanidza mativi matatu ese kune imwe angle, saka inoshandiswa kana iwe uchiziva mativi matatu kana maviri mativi uye iyo angle yakabatana. Mutemo wesines unobatanidza pedyo neangle yake yakanangana neangle uye unoshandiswa kana iwe uine mativi maviri akaenzana.
Nei SSA nguva dzose anopa maviri anokwanisa triangles?
Nemativi maviri neasina kusanganisira angle (mumwe muenzaniso wakaoma), iyo yakapihwa shure inogona kusvika pabasa panzvimbo mbiri dzakasiyana, saka ma triangles maviri akarurama anogona kusangana nedata rimwe chete. Calculator inozivisa izvi kana zvichiitika.
Chinogona kundiudza kana mavara angu haasi kuumba zvidimbu zviviri zvakaenzana?
Kana mativi akaparadza zvipingamupinyi zvetriangle (imwe nzvimbo iri yakareba kupfuura dzimwe mbiri dzakabatanidzwa) kana mativi haagone kusanganisira kusvika ku180 °, calculator inotaura kuti hapana setriangle iri kuwanikwa sezvakaitika pashure pekudzoka kwemhedzisiro.
