Answer:
If a^2 + b^2 =c^2, then the triangle is a right triangle.
Explanation:
Given
Shape: Triangle
Sides: a, b, c
Longest: c
Required
Select the true statements (See comment section for options)
From the options, we can see that we need to prove if the triangle is right-angled or not.
Since side c is the longest side, it means that side c is the hypotenuse.
Applying Pythagoras theorem
We have that:
If the above mathematical statement is true, then the triangle is right-angled
