What should be the conclusion for a math project on sum of three angles of a triangle is 180?

It depends on the level of the students. School students should conclude that this statement is true.
Higher level students should be able to conclude that the statement is only true in plane geometry. On a curved surface it is not true. On convex surfaces (bulging out), the angles add to more than 180 degrees, on concave surfaces (bulge in) they add to less than 180 degrees.
Graduate students should conclude that the statement is equivalent to Euclid's parallel postulate and so conclude that, if the statement is not always true, that demonstrates the existence of consistent non-Euclidean geometries.

How is it call a triangle with two angles that are complementary?
Complementary angles add up to ninety degrees. Triangles must hold 180. Taking these facts together, think of this: you have two angles in a triangle where they add up to ninety. This means that the other angle in the triangle must hold the other ninety. I'm not going to answer your question, but I'll pose you the question you should have asked: What is a triangle called when it has one angle that is exactly ninety degrees?
Is it possible to draw a right scalene triangle?
Yes it is. A normal, 3:4:5 triangle has a right angle, three different angles, and three different sides. There should be more for you to find.
Is there a relationship between a polygon's number of sides and its number of vertices and angles?
For a regular polygon, all sides are equal and all angles are equal. Draw a regular hexagon. This website shows you an easy way to draw a hexagon with a compass. http://www.wikihow.com/Draw-a-HexagonDraw a line from one vertex to another going thru the center. This should make 2 identical triangles. Do this, until you have 6 triangles. Use a protractor to measure the 6 angles in the center and the base angles. They should each be 60º angles. Two of these adjacent base angles measure 120º. This is the vertex angle. There are 6 vertices, 6 sides, 6 - 60º angles in the center, and 6 - 120º angles at the 6 vertices.1. If a polygon has n sides, there will be n angles at the center, n vertices and n triangles.2. Draw the 5 lines connecting each vertex to the center of the polygon making 5 angles.There are 360º around the center point, so 360º ÷ n is the measure of each angle at the center.The angle of the triangle at the center of the polygon = 360 º ÷ n. This angle is the angle of the triangle at the center of the polygon.The sum of the interior angles in a triangle = 180ºThe sum of the 2 base angles of each triangle must be 180 º - (360 º÷ n).Each of the base angles of the triangle must measure (180º - (360 º÷ n)) ÷ 2.Two adjacent base triangles from adjacent triangles form a vertex angle, so the vertex angle = 2* (180º - (360 º÷ n)) ÷ 2.Two adjacent base angles = one vertex angle.The vertex angle = 2 * (180º - (360 º÷ n) ÷ 2, which means you do not have to divide by 2. You can stop at step #6.Now let's try a sample problem. Here is a site for constructing a pentagon. http://www.kjmaclean.com/Geometry/PentConstruct.htmlFind the relationship between a pentagon's number of sides and its number of vertices and angles? Since a penta means 5, a pentagon has 5 sides, 5 vertices, and 5 angles. Now let's find the vertex angle.Since a penta means 5, a pentagon has 5 sides, 5 vertices, and 5 angles.5 angles360º ÷ 5 = 72ºThe angle of the triangle at the center of the polygon = 72º72 º + nº + nº = 180º180 º - (360 º÷ 5) = 108ºEach of the base angles of the triangle must measure 108º ÷ 2 = 54 ºThe vertex angle = 2* 54 º = 108ºNotice that the answer to #6 and #8 are the same.
How do you find the area of a rectangle with a triangle attached to the side?
you split your shape in half, (The rectangle and the triangle), by putting a line through it and then calculate the area of the rectangle and then calculate the area of the triangle, half the area of the triangle then add the area of the triangle and the rectangle together!Then you should have your answer!
How do you draw a right angle scalene triangle?
First lets define Scalene Triangle; It is a triangle with one right angle, the two other angles are unequal and none of the sides are equal. So to draw it, you have to follow a few steps; 1. Draw two perpendicular lines with one tip joining the tip of the other. 2. The length of both lines should not be equal. 3. Draw one more line to join the two ends of the lines. You will have your Right Angled Scalene Triangle. ======================================= -- Draw two line segments perpendicular, i.e. they meet at a corner. -- Make sure that they don't both end the same distance from the corner. -- Connect the the ends of the segments. -- Shazam. You have a right scalene triangle.
What is the 3 angles of a triangle?
I think this is what will answer your question. All 3 angles of a triangle should equal 1800
How many angels does a triangle has?
there should be 3 angles in a normal triangle......
How many equal angles does have a scalene triangle have?
no angles in a scalene triangle should be equal. its called a scalene triangle because none of the angles or sides ar similar or congruent.
The angles to a triangle should add up to how many degrees?
The angles of a triangle add up to 180 degrees.
Is it possible to draw one triangle with two right angles?
No it is not possible to draw 1 triangle with 2 right angles because the angles in a triangle should equal to 180 degrees
What would be the short conclusion for biology project made on oil spill?
Any conclusion should be based on what has been covered in the project. As we don't know what is in the project it is impossible to say what the conclusion would be.
Does a triangle have two right angels?
A triangle cannot have two right angles. Triangles angles should add up to 180. There are three angles. If there are 2 right angles, there would be no third angle, therefore, no triangle. XD
When a triangle is enlarged by a factor 3 are the angles tripled in size?
No - if the lengths of the sides are all increased by a factor of 3, the angles remain unchanged. You just wind up with a "similar" triangle 3 times the size of the original. A quick counterexample would be to consider what would happen if the angles DID change. The sum of the angles in the original triangle should be 180°. If the angles in the new, larger triangle tripled in size, the sum of the angles in the bigger triangle would be 540° - but the sum of the angles of a triangle should always remain 180°.
What should be the conclusion for a math project on games with numbers?
The conclusion should be that everyone had a good time and learned something.
Why a triangle should have at least two acute angles?
Because the 3 interior angles of any triangle add up to 180 degrees.
How do i answer my conclusion on tropical cyclone project?
Wikianswers will not do your homework for, but it can offer advice. The conclusion will depend on what you discuss in your project, but in general it should summarize the basic ideas drawn from the project.
What should the sum of the angles of a triangle equal?
180 degrees
