The school geometry worksheet asked us to prove that the hypotenuse of a right-angled triangle is the longest side.

In the diagram, the shaded region is part of an obtuse-angled triangle whose longest side measures 10 cm.

The teacher asked the students to classify each triangle on the worksheet and to identify any acute-angled triangle.

In the geometry class, we explored several obtuse-angled triangles and calculated their areas.

During the staff meeting, several Karpman drama triangles emerged, complicating efforts to resolve the conflict.

In therapy, recognizing the Karpman drama triangle helped the group members stop assigning fixed roles and start communicating more honestly.

In the geometry class, we compared the areas of several right-angled triangles to understand the Pythagorean theorem.

The three statues were arranged trianglewise around the fountain, giving the plaza a balanced, harmonious feel.
