Trigonometry Examples

$8$ , $10$ , $12$

Step 1

Check if the three sides make the pythagorean theorem true.

$8^{2} + 10^{2} = 12^{2}$

Step 2

Determine if $8^{2} + 10^{2} = 12^{2}$ is true.

Step 2.1.1

Raise $8$ to the power of $2$ .

$64 + 10^{2} = 12^{2}$

Step 2.1.2

Raise $10$ to the power of $2$ .

$64 + 100 = 12^{2}$

Step 2.2

Add $64$ and $100$ .

$164 = 12^{2}$

Step 2.3

Raise $12$ to the power of $2$ .

$164 = 144$

Step 3

Since $164 \neq 144$ , the three sides do not form a right triangle.
