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.

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

The physics lab measured the critical angles for different glass samples to study light refraction.

The architect adjusted the oblique angles of the glass facade to reduce glare and enhance privacy.

The architect favored canted angles in the facade to catch more light.

The torsion angle between the plane containing atoms A, B, C and the plane containing B, C, D critically influences the molecule's conformation.

To compute the area of the spherical triangle, we first measured each spherical angle formed by the intersecting great-circle arcs.
