Given:

One midsegment of an equilateral triangle.

To find:

The ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths.

Solution:

All sides of an equilateral triangle are same.

Let a be the each side of the equilateral triangle.

Length of the midsegment is equal to the half of the non included side or third side.

Midsegment=\dfrac{a}{2}

The sum of two side is

a+a=2a

Now, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is

\text{Required ratio}=\dfrac{\text{Length of midsegment}}{\text{sum of two sides}}

\text{Required ratio}=\dfrac{\dfrac{a}{2}}{2a}

\text{Required ratio}=\dfrac{a}{4a}

\text{Required ratio}=\dfrac{1}{4}

\text{Required ratio}=1:4

Therefore, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is 1:4.
