Question

If a right triangle has sides 5, 12, and 13 units, then a triangle with sides 10, 24, and 26 is also a right triangle.(1 point)

True, because multiples of a right triangle triple produces a similar right triangle with congruent angles.

False, because doubling the sides of the triangle does not keep the angles congruent

Answer 1

True — because scaling a Pythagorean triple preserves the Pythagorean relation (and angles). Check: 10^2 + 24^2 = 100 + 576 = 676 = 26^2, so the triangle is right.
