How many triangles can be drawn with side lengths 3, 5, and 9?
A.
0
B.
1
C.
2
D.
3
Need help pls help
3 + 5 = 8
therefore the two short sides are too short to reach the ends of the long side.
thanks to the people who help me
Hey anonymous so does this mean you cant make any
To determine how many triangles can be drawn with side lengths of 3, 5, and 9, we can use the triangle inequality theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
In this case, we have sides of lengths 3, 5, and 9. Let's consider all three possibilities:
1. 3 + 5 > 9: This condition is met, so we can form a triangle using these side lengths.
2. 5 + 9 > 3: This condition is met, so we can form another triangle using these side lengths.
3. 3 + 9 > 5: This condition is not met, as 3 + 9 = 12 is not greater than 5. Therefore, we cannot form a triangle with these side lengths.
Based on these conditions, we can conclude that only two triangles can be drawn with side lengths 3, 5, and 9. Therefore, the correct answer is C. 2.
