Geometric Analysis: Identifying Acute Triangles from Diagrams

Is the triangle in the drawing an acute-angled triangle?

To solve this problem, we need to determine if the triangle depicted is an acute-angled triangle.

An acute-angled triangle is defined as a triangle where all internal angles are less than $90^\circ$.

Upon observing the triangle in the drawing, it appears that each of its angles is less than $90^\circ$. The shape of the triangle does not present any right angles ($90^\circ$) or angles greater than $90^\circ$.

Thus, based on the visual inspection and understanding of triangle properties, the triangle appears to be acute-angled.

Therefore, the solution to the problem is Yes, the triangle is an acute-angled triangle.
