Prove that the perimeter of a quadrilateral is greater than the sum of the length of its diagonal?
The shortest path between two points is a straight line. This is a mathematical fact, which can be proven in another question.The diagonal of a quadrilateral is a straight line between two opposing (non-adjacent) vertices. The perimeter of a quadrilateral will include two separate paths between the same vertices. The difference is that these two paths are each composed of two linked line segments, so each of these paths will be longer than the diagonal.Therefore, the length of the perimeter of a quadrilateral will be greater than twice the length of either diagonal.
suppose you want to prove the isosceles triangle theorem by proving that JKL?

How to prove an isosceles triangle with one angle bisector?
What have we got to prove? Whether we have to prove a triangle as an Isoseles triangle or prove a property of an isoseles triangle. Hey, do u go to ALHS, i had that same problem on my test today. Greenehornet15@yahoo.com
How can you prove that the is the sum of the lengths of any two sides of a triangle always greater than the length of the third one?
Simply measure them.
How do you prove triangle only one obtuse angle?
Sum of angles of triangle = 180o: minimum size of obtuse angle is greater than 90o; It is not possible to have two angles of a triangle which total more than 180o.
Does pythagorean theorem prove a triangle to be a right triangle?
Yes
How do you prove an isosceles triangle?
an isisceles triangle is a triangle with atleast two sides congruent.
How can proving two triangles congruent can help prove parts of the triangle congruent?
When you prove a triangle is congruent to another, it can help you prove parts of the triangle congruent by checking the ratio between all sides and angles. Thank you for asking
How do you prove a right angle triangle?
You cannot prove "a right angle triangle". You may or may not be able to prove statements about right angled triangles but that will depend on the particular statement.
Why is AAA not an appropriate conjecture for triangle congruence?
It does not necessarily prove congruence but it does prove similarity. You can have a smaller or bigger triangle that has the same interior angles.
Which postulate or theorem can you use to prove that triangle ABC triangle EDC?
ASA
What is an example of a Lemma?
An example of a lemma in mathematics is the triangle inequality, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Lemmas are used as stepping stones to prove more complex theorems.
How do you prove that isosceles triangles have three equal sides?
If You Prove An Isosceles Triangle To Have Three Equal Sides. You Now Have Disproved It As Being An Isosceles Triangle. So Even If You Could You Would Now Have An Equilateral Triangle. I Just Can`t See A Way This Can Be Done.
How can you prove that a triangle is an isosceles triangle with some examples?
An isosceles triangle has 3 sides 2 of which are equal in length An isosceles triangle has 3 interior angles 2 of which are the same size
