Triangle Similarity - Finding Unknown Length

MathematicsSimilarity in TrianglesEasy

Published:

Given the diagram of the nested triangles, find the value of $x$.

Inner side length: $4$

Outer segment length: $6$

Inner base length: $2$

Outer base length: $x$

This question includes visual content: A hand-drawn diagram on graph paper showing two nested triangles sharing a top vertex. The smaller triangle sits inside a larger one, and their bases are presumably parallel. The left side of the smaller triangle is labeled '4'. The left side of the larger triangle has a remaining segment labeled '6' below the first segment (making the total side length 10). The base of the small triangle is labeled '2'. The base of the large triangle is labeled 'x'.

Step by Step Written Solution

1
Step 1

Merhaba! Bu soruda, benzer üçgenleri kullanarak x değerini bulacağız.

Üçgende Benzerlik

2
Step 2

Şekilde birbirine paralel iki taban görüyoruz. Bu durum, üstteki küçük üçgenin büyük üçgene benzer olduğu anlamına gelir.

462x
3
Step 3

Benzerlik oranını kurarken, küçük üçgenin yan kenar uzunluğunun büyük üçgenin toplam yan kenar uzunluğuna oranını kullanırız.

$$\frac{\text{Küçük Kenar}}{\text{Büyük Kenar}} = \frac{\text{Küçük Taban}}{\text{Büyük Taban}}$$
4
Step 4

Küçük üçgenin kenarı dört birimdir. Büyük üçgenin kenarı ise dört artı altıdan toplam on birimdir.

$$4 + 6 = 10$$
5
Step 5

Şimdi bu değerleri oranımızda yerine koyalım. Dördün ona oranı, ikinin x'e oranına eşittir.
