Understanding Acute-Angled Triangles
An acute-angled triangle is a specific type of triangle defined by the measures of its angles. Here’s a detailed explanation of why option 'D' is the correct choice:
Definition of Acute-Angled Triangle
- An acute-angled triangle is one where all three angles are less than 90 degrees.
- This means that each angle contributes to a total of less than 270 degrees when combined.
Analyzing the Options
- Option A: One angle is equal to 90 degrees.
- This describes a right-angled triangle, not an acute-angled triangle.
- Option B: Two angles are equal.
- While an acute triangle can have equal angles (e.g., an equilateral triangle), this does not specifically define an acute-angled triangle.
- Option C: One angle is greater than 90 degrees.
- This describes an obtuse-angled triangle, which is the opposite of an acute-angled triangle.
- Option D: All angles are less than 90 degrees.
- This is the correct definition of an acute-angled triangle, confirming that it meets the criteria.
Conclusion
In summary, an acute-angled triangle is characterized by the fact that all its angles are less than 90 degrees. This property distinguishes it from other types of triangles, making option 'D' the correct answer. Understanding these definitions enhances knowledge in geometry and helps in identifying different types of triangles.
