Given triangles ABC and A1B1C1, angle A = A1, B = B1, their sides are proportional. Will they be the same?
| September 28, 2021 | education
Because the angle of triangle A is equal to the angle of triangle A1, and the angle of triangle B is equal to the angle B1, and the sum of the angles in any triangle is 180 degrees, this means that the angle of triangle C is equal to the angle of triangle C1, it turns out that the angles of these triangles are equal, and the sides are proportional, this is given from the condition of the problem. Based on the data, we can say that the triangles are similar to each other, which was required to be proved.
Answer: triangles are similar.
