exterior angle theorem
If all angles in a triangle are equal to 60 degrees, then the triangle is an equilateral triangle. In an equilateral triangle, all three sides are equal in length. This property is a consequence of the triangle angle sum theorem, which states that the sum of the interior angles of a triangle is always 180 degrees. Therefore, if each angle is 60 degrees, the total sum of the angles in the triangle is 180 degrees, satisfying the theorem.
Two of the sides wouldn't join. So it would't be a triangle.AnswerAccording to the Triangle Sum Theorem, a Triangle's three angles add up to 180o. It is impossible for there to be 2 out of 3 angles that add up to 180o, since the Triangle Sum Theorem says that all 3 angles must add up to 180o.
It is a right angle triangle and the sum of its squared sides is equal to its squared hypotenuse in accordance with Pythagoras' theorem
If you are referring to Pythagoras' theorem for right angle triangles then the theorem states that for any right angle triangle the square of its hypotenuse is equal to the sum of its squared sides.
The theorem that states every triangle's angles add up to 180 degrees
The sum of all inner angles within a triangle is 180 degrees.
complementary
The sum of the interior angles of a triangle in euclidean geometry equal 180 degrees
The triangle inequality theorem states that any side of a triangle is always shorter than the sum of the other two sides.
triangle sum theorem
Pythagoras' theorem is only applicable to a right angle triangle in that the square of its hypotenuse is equal to the sum of its two squared sides.
The converse of Pythagoras's theorem states :- "If the square of one side of a triangle is equal to the sum of square of other two sides then the triangle is a right angled triangle""
A triangle is a right triangle if the sum of the squares of the two legs is equal to the square of the hypotenuse.
It is Pythagoras' theorem that states for any right angle triangle its hypotenuse when square is equal to the sum of its squared sides.
