[tex]\begin{gathered} PQ\text{ = 3} \\ QR\text{ = 3} \end{gathered}[/tex]
Here, we want to calculate the measure of the two sides
As we can see, what we have is the measure of the hypotenuse
It is the side that faces the right-angle and also it is the longest side
The triangle is a 45-90-45 triangle
The measure of the opposite and the adjacent are the same
The ratio of the sides are;
[tex]1\colon1\colon\sqrt[]{2}[/tex]
We already have the root 2 part
So to get the value of the 1 ratio, we need to divide the hypotenuse by root 2
Mathematically, we have this as;
[tex]\frac{3\sqrt[]{2}}{\sqrt[]{2}\text{ }}\text{ = 3}[/tex]
