Which theorem states that the measure of an exterior angle in a triangle is the sum of its remote interior angle measures?
exterior angle theorem
All angles in a triangle equal 60 degrees?
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.
Why cant a triangle have 2 right angles?
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.
How are the side lengths of a 30º60º90º triangle related?
It is a right angle triangle and the sum of its squared sides is equal to its squared hypotenuse in accordance with Pythagoras' theorem
Is L a theorem is all about right triangles?
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.
