cara menghitung rumus segitiga

formula Luas Segitiga

Luas = ½ x alas x tinggi
L = ½at

rumus di atas asli untuk seluruhnya kategori segitiga, baik segitiga sama kaki, sama segi siku-siku maupun segitiga sembarang. awal rahasia di atas, kita mampu mencari alas suatu segitiga bila luas dan tingginya didapati Kita tengah dapat mencari tinggi sebuah segitiga jikalau luas dan alasnya ketahuan diawal mulanya untuk kalian yg mau lebih luas pengetahuanya dalam menghafal kiat mampu menyebut di kumpulan metode matematika yang sudah admin jadikan satu label.

Ok sebelumnya sahabat dapat pun teliti beberapa rahasia semenjak bangun datar yang telah ana sajikan dalam artikel sebelumnya mulai sejak alamat cara volume tabung, setelah itu sohib bisa belajar kembali resep kapasitas krucut dimana ke tiga bagun datar ini tukar tergantung satu bersama yg lainya. seandainya telah teliti yuk dibawah ini trick luas segitiga yang administrator hadirkan buat sohib di rumah.

L = ½at
2L = at
a = 2L/t
t = 2L/a

sample soal
Berikut ini contoh pertanyaan yang bersambung dengan luas segitiga beserta penelitian dan jawabannya.

1. diketahui sebuah segitiga siku-siku bersama alas 14 centi meter dan tinggi 16 senti meter Berapakah luas bangun tersebut?

L = ½ x 14 x 16 = 112 cm²

2. suatu segitiga luasnya 42 senti meter seandainya tingginya 12 cm berapakah panjang alas segitiga tersebut? dengan menggunakan rumus segitiga berikut ini apkah anda bisa menyelesaikannya dengan cepat

L = ½ x alas x tinggi
42 : ½ = alas x 12
84 = alas x 12
alas = 84/12
alas = 7 cm

3. Luas suatu segitiga ialah 96 senti meter jikalau panjang alasnya 12 centimeter tentukan tinggi segitiga tersebut!

L = 96
L = ½at
96 = ½ x 12 x t
96 : ½ = 12 x t
192 = 12 x t
t = 192/12
t = 16 cm

4. Panjang sudut istimewa dan alas segitiga siku-siku berenteng-renteng yaitu 20 cm dan 24 centi meter Berapakah luas segitiga tersebut?

20² = t² + 12² → 12 bermula mulai sejak ½ panjang alas
t² = 20² – 12²
t² = 400 – 144
t² = 256
t = √256
t = 16 cm

L = ½ x 24 x 16 = 192 cm²

5. ketahuan keliling segitiga sama kaki ialah 16 centi meter jika panjang alasnya 6 centi meter berapakah luasnya?

panjang 2 sisi asing = keliling – alas = 16 – 6 = 10 cm
panjang jalan berlawanan sisi sedeng = 10 : 2 = 5 cm

t² = 5² – 3² → 3 awal alamat ½ x alas
t² = 25 – 9
t² = 16
t = √16
t = 4 cm

L = ½ x 6 x 4 = 12 cm²

The cols theme looks better with longer posts, so we’ll fill this one out with some filler text. ‘I’ll fetch the executioner myself,’ said the King eagerly, and he hurried off.

Alice thought she might as well go back, and see how the game was going on, as she heard the Queen’s voice in the distance, screaming with passion. She had already heard her sentence three of the players to be executed for having missed their turns, and she did not like the look of things at all, as the game was in such confusion that she never knew whether it was her turn or not. So she went in search of her hedgehog.

The hedgehog was engaged in a fight with another hedgehog, which seemed to Alice an excellent opportunity for croqueting one of them with the other: the only difficulty was, that her flamingo was gone across to the other side of the garden, where Alice could see it trying in a helpless sort of way to fly up into a tree.

By the time she had caught the flamingo and brought it back, the fight was over, and both the hedgehogs were out of sight: ‘but it doesn’t matter much,’ thought Alice, ‘as all the arches are gone from this side of the ground.’ So she tucked it away under her arm, that it might not escape again, and went back for a little more conversation with her friend.

When she got back to the Cheshire Cat, she was surprised to find quite a large crowd collected round it: there was a dispute going on between the executioner, the King, and the Queen, who were all talking at once, while all the rest were quite silent, and looked very uncomfortable.

The moment Alice appeared, she was appealed to by all three to settle the question, and they repeated their arguments to her, though, as they all spoke at once, she found it very hard indeed to make out exactly what they said.

The executioner’s argument was, that you couldn’t cut off a head unless there was a body to cut it off from: that he had never had to do such a thing before, and he wasn’t going to begin at HIS time of life.
