Step 1:I'll solve this step-by-step:
Step 2:: Analyze the definition of a triangle
A triangle is a two-dimensional geometric shape with specific characteristics: - It must be formed by line segments - It requires exactly three points - These points must NOT be on the same straight line (noncollinear)
Step 3:: Evaluate each option carefully
Loading...
- Contains exactly three segments - Requires points to be noncollinear - Matches the precise mathematical definition of a triangle - Contains four segments - This describes a quadrilateral, NOT a triangle - Incorrect definition - Points are on the same line - Cannot form a closed shape - Incorrect definition - Parallel segments cannot enclose a two-dimensional area - Incorrect definition
Final Answer
A figure formed by three segments connecting three noncollinear points
