How many angles does a triangle have

WebThree vertices and three sides constitute a triangle. Triangles have a total angle of 180° if all internal angles are added together. Three sides of a triangle are longer than their sum if two of them are longer than the third. When a triangle has more than one angle, the opposite side is the largest. WebA right-angled triangle will have one angle that is 90°, which means the other two angles will have a total of 90°. A scalene triangle will have all angles of a different size.
