Write the definition as a biconditional statement. A triangle which has no congruent sides is a scalene triangle.

1. A triangle is scalene if and only if it has no sides that are congruent.
2. A triangle is obtuse if and only if it has no sides that are congruent.
3. A triangle is not scalene if and only if it has no sides that are congruent.
4. A triangle is scalene if and only if it has two or less congruent sides.

step-by-step explanation:

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
