A triangle cannot have more than one right angle
The triangle was known in China in the early 11th century by the mathematician Jia Xian (1010–1070)
A triangle has 3 medians and 3 altitudes. The outer angle of a triangle is equal to the sum of the opposite angles inside it. ∠ACD = ∠A + ∠B. Total Angle Properties: The sum of the three angles of the triangle is 180 °.
A triangle is a closed two-dimensional shape with three sides, three angles, and three vertices. Triangles are also polygons. The figure above is a triangle labeled △ ABC. Triangle example. Practical examples of triangles include sandwiches, traffic signs, hangers, and pool tables.
The three angles in the triangle, called the internal angles, always add up to 180 °. The sides that form an angle (the sides next to it) are called the adjacent sides of the angle. The opposite side (the side that crosses an angle and does not form part of it) is called the opposite side of the angle.
