Which are the possible side lengths of a triangle? 3 cm, 5 cm, 9 cm 4 cm, 8 cm, 10 cm 6 cm, 9 cm, 17 cm 8 cm, 10 cm, 18 cm

- 4 cm, 8 cm, 10 cm are the possible side lengths of a triangle.

Explanation:-

We know that in a triangle the sum of any two sides of a triangle must be greater than the third side.

Given :

1. Measurement of first triangle=3 cm, 5 cm, 9 cm

Now, for triangle Sum of two sides > third side

⇒3+5>9

⇒8>9 , which is not true.

∴ Triangle with these side lengths is not possible.

2.Measurement of second triangle=4 cm, 8 cm, 10 cm

Now, for triangle Sum of two sides > third side

⇒4+8>10⇒12>10, which is true.

⇒8+10>4⇒18>4, which is true.

⇒4+10>8⇒14>8, which is true.

∴Triangle with these side lengths is possible.

3. Measurement of third triangle=6 cm, 9 cm, 17 cm

Now, for triangle Sum of two sides > third side

⇒6+9>17⇒17>17 , which is not true.

∴Triangle with these side lengths is not possible.

4. Measurement of fourth triangle=8 cm, 10 cm, 18 cm

Now, for triangle Sum of two sides > third side

⇒8+10>18⇒18>18 , which is not true.

∴Triangle with these side lengths is not possible.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
