In an isosceles triangle, if the longest side (c) is the base of the triangle and the other two sides (a) are the equal sides, you can use the Pythagorean theorem to determine if the triangle is a right triangle.
For a triangle to be a right triangle, the relationship between the sides must satisfy the equation:
\[ a^2 + b^2 = c^2, \]
where c is the length of the hypotenuse (in this case, c would be the longest side, which is c), and a and b would be the lengths of the other two sides (both a).
However, since this is an isosceles triangle and the two equal sides are both a, we can denote the two equal sides as a units. If we assume one a side is perpendicular to the base c when forming a right triangle, the correct relationship to check if it forms a right triangle would simplify to:
\[ 2a^2 = c^2. \]
Thus, among the options provided, the correct equation that can indicate if the triangle is a right triangle is:
\[ 2a^2 = c^2. \]
Therefore the answer is:
**2 a squared = c squared.**
