Question

Define and state the three properties of a triangle with figure:.
(a) Angle Sum Property. (b) Exterior Angle property. (c) Pythagora'' theorem ​

Answer 1

Angle Sum Property

The properties of the triangle are: The sum of all the angles of a triangle(of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

Exterior Angle Property

The exterior angle of a given triangle equals the sum of the opposite interior angles of that triangle. If an equivalent angle is taken at each vertex of the triangle, the exterior angles add to 360° in all the cases.

Pythagoras Theorem

The properties of the triangle are: The sum of all the angles of a triangle(of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
