Question

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

Answer 1

Answer:

it is none

Step-by-step explanation:

i got a 80 becasue its not one its none just took the test

Answer 2

Answer:  one

Reason:

The SSS (side side side) congruence rule says that two triangles are congruent if we have three pairs of sides that are the same length. Any triangle you construct that has side lengths 15, 7, and 5 will be congruent to the original triangle by the SSS rule. You may have to translate, rotate or reflect the second triangle so that it lines up perfectly with the first triangle.

Alternatively, consider triangle ABC that is the given triangle. Let AB = 15, BC = 7, and AC = 5. Then consider another triangle DEF such that DE = 15, EF = 7, and DF = 5. It is possible to do a series of translations, rotations, or reflections such that we get triangle DEF to overlap triangle ABC perfectly.
