How many triangles can be constructed with sides measuring 15cm, 7cm, and 5 cm? a. one b. none c. more than one

Here we must see how many triangles can be made with the given sides, we will see that there is only one triangle that can be made with these sides.

So we have 3 sides:

Remember that a triangle is defined by its sides and angles, if we have 3 known sides, then we have 3 known angles, thus there is only one triangle that can be made, as all the possible things that make the triangle are already defined.

Remember that for example, we can make a triangle with these sides and apply a rotation to it, so the triangle and the image of the rotation will look different, but the figure will be exactly the same for any rotation.

So we can make only one triangle with 3 defined sides, so the correct option is A, one.
