WebAug 23, 2024 · In fact, you can draw a triangle on the Earth that has three right angles [2], making an angle sum of 270°. Triangle with three right angles on a sphere. On a sphere like the Earth, the angle sum is not constant among all triangles. Bigger triangles have bigger angle sums, and smaller triangles have smaller angle sums, but even tiny …
Can a triangle have 3 right angles
Did you know?
WebA triangle cannot be right-angled and obtuse-angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle and vice versa. The side opposite the obtuse angle in the triangle is the longest.
