Question

Determine the symbol that will complete this damment that would be used in order to determine whether angle pee is a right triangle. Is the correct answer ABC or D?

Answer 1

In order to determine whether P is a right angle, we will apply the Pytyhagoras theorem.

The formula is,

$\text{Hypotenuse}^2=Opposite^2+Adjacent^2$

where,

$\begin{gathered} Hypotenuse=QR=29inches \\ \text{Opposite}=PR=21\text{inches} \\ \text{Adjacent}=PQ=20\text{inches} \end{gathered}$

Therefore,

$29^2=21^2+20^2$

Simplify

$\begin{gathered} 841=400+441 \\ 841=841 \end{gathered}$

Hence, the correct answer is

$20^2+21^2=29^2\text{ (OPTION 4)}$
