Right Triangle Identification: Analyzing Triangle Properties from a Diagram

Question

Is the triangle in the drawing a right triangle?

00:00 Determine whether the triangle is right-angled

00:04 Draw perpendiculars to the sides that create right angles

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

00:25 Therefore, the triangle is acute-angled

00:30 This is the solution

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.
