WebApr 9, 2024 · If a triangle is not planar, for example if it is lying on the curved surface of a sphere, the angles do not add up to 180. 09 Apr 2024 17:31:11 WebIn plane geometry, constructing the diagonal of a square results in a triangle whose three angles are in the ratio 1 : 1 : 2, adding up to 180° or π radians. Hence, the angles respectively measure 45° (π / 4), 45° (π / 4), and 90° (π / 2).The sides in this triangle are in the ratio 1 : 1 : √ 2, which follows immediately from the Pythagorean theorem.
