An angle sum property states that the sum of the angles in a triangle is always equal to 180 degrees. This means that if you have any three points A, B, and C in a triangle, the angle sum of the triangle is equal to 180 degrees.
Here's a more formal definition:
Angle Sum Property: For any triangle ABC, the sum of the angles A, B, and C is equal to 180 degrees.
Here are some examples of how this property works:
In any triangle ABC, the sum of the angles A, B, and C is equal to 180 degrees if point C lies on the line segment AB.
In the triangle ABC with points A = 30 degrees, B = 45 degrees, and C = 55 degrees, the angle sum is also equal to 180 degrees.
In the triangle ABC with points A = 60 degrees, B = 70 degrees, and C = 50 degrees, the angle sum is also equal to 180 degrees.
The angle sum property is a theorem, which means it is a statement that is always true for any triangle. This means that you can use the angle sum property to prove other theorems about triangles, such as the Pythagorean theorem
