Te tātaitai tapawhā
Whakarautaki i tētahi tapawhā mai i ngā taha me ngā koki — te rohe, te pereti me ngā uara kāore.
Ka tāuru i ngā uara 3 (he taha iti rawa). Ko ngā taha a, b, c he koki ātete A, B, C.
E toru ngā uara ki te whakaoti.
Mo tēnei tātaitai
you have a triangle, you can use the law of cosines to find the area of the triangle. It is a simple calculator that can be used to find the area of a triangle. It is a simple calculator that can be used to find the area of a triangle. It is a simple calculator that can be used to find the area of a triangle. It is a simple calculator that can be used to find the area of a triangle. It is a simple calculator that can be used to find the area of a triangle. It is a simple calculator that can be used toFor a worked example, entering the three sides 3, 4 and 5 identify a right triangle from the values you know (three sides, two sides and an angle, or two angles and a 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 area.
Ko nga pātai e pā ana
He aha te mea e hiahiatia ana e au kia whakaoti i tētahi tapawhā?
E toru ngā uara e whakauru ana ki tētahi taha iti rawa: e toru ngā taha (SSS), e rua ngā taha me te koki whakauru (SAS), e rua ngā koki me te taha (ASA/AAS), e rua rānei ngā taha me te koki kāore i roto (SSA).
He pēhea te tatau i te rohe?
Mai i ngā taha e toru ka whakamahia te tātai a Heron; me ngā taha e rua me te koki kua whakaurua ka whakamahia e ia te ½ × a × b × sin(C). Ka hoatu e rāua te hua ōrite mō tētahi tapawhā tika.
He pēhea te whakaoti i tētahi tapawhā 3-4-5?
Ka tāuru i ngā taha e toru hei 3, 4 me te 5 me te waiho i ngā koki pōuri. Ka whakaū te tātaitai he tapawhā tika me te koki 90° e ātete ana ki te taha o te roanga 5, ngā koki tata ki te 36.87° me te 53.13°, te rohe 6 me te perimeter 12.
He aha te rerekētanga i waenganui i te ture o ngā kōaro me te ture o ngā kōaro?
Ko te ture o ngā kōaro e hono ana i ngā taha katoa e toru ki tētahi koki, nō reira ka whakamahia ina mōhio koe ki ngā taha e toru, ki ngā taha e rua rānei me te koki i whakaurua. Ko te ture o ngā kōaro e hono ana i tētahi taha ki tōna koki ā-kiri, ā, ka whakamahia ina whai tētahi takirua koki-wāhi ōrite.
He aha te āhua o te SSA i ētahi wā e rua ngā tapawhā e taea ai?
Me ngā taha e rua me tētahi koki kāore i roto (te take ā-whakaaro), ka tae te taha i tukuna ki te pūtake i ngā wāhi rerekē e rua, kia ōrite ai ngā tapawhā tika e rua ki te tātai ōrite. Ka tohu te tātaitai i tēnei ina puta.
Ka taea e ia te kī ki a au mēnā kāore a ahau i te hanga i tētahi tapawhā tika?
Inā whakawātea ngā taha i te taumahatanga o te tapawhā (he roa ake tētahi taha i ētahi atu e rua i whakakotahitia), kāore rānei e taea te tāpiri i ngā koki ki te 180°, ka pūrongo te tātaitai kāore he tapawhā pēnei i te whakamutu i te hua.
Ko ngā hua he whakataunga mō te tohutohu ahuwhānui anake, ehara i te tohutohu moni, rongoā, tāke rānei.
