Where did the polygon name for triangle come from?
The name of a triangle came from the number of angles it has, 'tri' meaning three.
Where does the formula for the sum of interior angles of a polygon come from?
Euclid parallel postulate can be interpreted as being equivalent to the sum of the angles of a [plane] triangle being 180 degrees. It is quite easy to prove that a polygon with n sides can be divided into n triangles. Putting the two together, you get the formula for the sum of the interior angles of a polygon.
Is it possible to get a right angeled equilateral triangle?
No, because angels don't come to earth for triangles. However, you can certainly have right angled equilateral triangles.
How many vertices does a right triangle have?
3. Vertex (singular of Vertices) is the POINT of the sides (ray, segment, line) come together. For any triangle it always has 3 angles, and thus 3 points, which means 3 vertices. A right triangle is still an triangle, only that one of the 3 angles being 90 degree.
Which shape has 3 straight sides and no right angles?
Ah, what a lovely question! The shape you're thinking of is a triangle. Triangles have three straight sides and no right angles. They come in all different sizes and can be found in nature and in art. Just imagine all the beautiful landscapes you could create with triangles!
Is a ray a polygon?
No, a ray is a straight line with no ending points. And a polygon has lines that come together at points.
Who discovered polygon?
The ancient Greeks because polygon come from a Greek word meaning 'many sides'
What does the saying of the triangle is the only rigid polygon mean?
Well, isn't that just a happy little saying! You see, a triangle is made up of three sides and three angles, which gives it stability and rigidity. Unlike other polygons that can change shape or collapse, a triangle always keeps its form, just like a strong foundation in a painting. So, remember, just like a triangle, stay true to your values and beliefs, and you'll stand strong no matter what challenges come your way.
A right triangle is 35 degrees What is the measure of the other triangle?
question doesn't make sence but i sort of know what your getting at.if you have a right hand triangle and one of the other angles is 35 deg then what is the remaining angle's angle.all triangles angles added together come to 180dega right angle is 90degso 90 + 35 = 125180 - 125 = 55the remainding angle is 55deg.
How did the Pythagorean theorem come about?
It was noticed by ancient mathematicians that for any right angle triangle that when its hypotenuse is squared it is equal to the sum of its squared sides.
Where did the name for a triangle come from?
Tri means three. And there are three angles to a triangle.
Why is the sine of an angle less than 1?
In a right triangle, the sine of the angle is equal to the (leg opposite the angle) divided by the (hypotenuse). It's well known that the hypotenuse is always the longest side in the right triangle, so this division can never come out to be more than ' 1 '.
