Which equation is a true equation based on the right triangle shown?

Question

Option 1:  p2+t2=s2

Option 2:  p2+s2=t2

Option 3: There is not enough information about the triangle to write an equation.

Enter "1", "2", or "3".

Answer 1

Option 1: p^2 + t^2 = s^2

This equation is not a true equation based on the right triangle shown. The correct equation for a right triangle is the Pythagorean theorem, which states that the sum of the squares of the lengths of the two legs (p and t) is equal to the square of the length of the hypotenuse (s). Therefore, the correct equation should be:

Option 2: p^2 + t^2 = s^2
