Right Triangle Identification: Analyzing Triangle Properties from a Diagram

Question

Is the triangle in the drawing a right triangle?

00:00 Is the triangle right-angled?

00:04 Let's draw perpendiculars to the sides that create right angles

00:08 We can see that each angle in the triangle is less than 90° (acute)

00:25 Therefore, the triangle is acute-angled

00:30 And this is the solution to the question

It can be seen that all angles in the given triangle are less than 90 degrees.

In a right-angled triangle, there needs to be one angle that equals 90 degrees

Since this condition is not met, the triangle is not a right-angled triangle.
