A ladder is leaning against a wall to form a triangle with the ground and the wall. The length of the ladder is 12 feet. The distance from the wall to the base of the ladder is 6 StartRoot 2 EndRoot Feet. The wall and the floor form a right angle. A 12-foot ladder is leaning against a wall. The distance from the base of the wall to the base of the ladder is 6 StartRoot 2 EndRoot feet. Given this information, what can be determined about the triangle formed by the ground, wall, and ladder? Check all that apply.

The triangle is isosceles.
The leg-to-hypotenuse ratio is 1:StartRoot 2 EndRoot.
The leg-to-hypotenuse ratio is 1:StartFraction StartRoot 2 EndRoot Over 2 EndRoot.
The nonright angles are congruent.
The ladder represents the longest length in the triangle.
