What is the best definition of triangle?
A triangle is a three-sided polygon defined by three vertices connected by three straight edges. The sum of the internal angles in a triangle always equals 180 degrees. Triangles can be classified based on their sides (equilateral, isosceles, and scalene) or their angles (acute, right, and obtuse).
What is the center of rotation in a tr iangle?
The center of rotation in a triangle typically refers to the centroid, circumcenter, or incenter, depending on the context. The centroid is the point where the three medians intersect and serves as the triangle's center of mass. The circumcenter is the point where the perpendicular bisectors of the sides meet, equidistant from all vertices, while the incenter is where the angle bisectors converge, equidistant from all sides. Each point serves distinct geometric purposes within the triangle.
Is it possible to make a 1 by 2 by 3 triangle?
NO!!! The sum of the two shorter sides MUST exceed the longest side. 1 + 2 = 3 ; 3 So the sum does not satisfy the criteria.
What is the law of cosines?
It is a mathematical equation that allows you to "solve" a triangle (find all length and angle values), if you know 2 sides and an included angle, or all three sides. It doesn't have to be a right triangle. You can find the cosine on a calculator easily.c2 = a2 + b2- 2ab cos CC = included anglec = side opposite angle C (c)a = side ab = side bThe cosine law relates the length of the sides of a triangle to one of the angles in the triangle. If the triangle is labelled with vertices A, B, C with usual notation for edges (ie a is the side opposite the vertex A, so not touching A) and if x is the angle at vertex C then the cosine law says (c^2)=(a^2)+(b^2)-2abcos(x)
Which point in a triangle is equidistant from the vertices's of the triangle?
Not sure about vertices's. The circumcentre is equidistant from a triangle's vertices (no apostrophe).
What are vertices from a triangle?
The vertices of a triangle are the endpoints. In other words, when the sides of the triangle intersect, they form a vertex of a triangle. A triangle has a total of three vertices.
Does a right angled triangle have vertices?
Vertices are the main property of triangles. No vertices, no triangle.
What shape has 3 vertices?
A triangle has 3 vertices.
What are the vertices's of a triangle?
They are the 3 corners of the triangle and vertices is the plural of vertex
How many vertices triangle have?
A triangle has 3 vertices and 3 sides
Is the centroid equidistant from the vertices's of a triangle?
No. and it is not vertices's! vertices will do.
Which polygon has less than 4 vertices?
A triangle has three vertices.
Do a triangle and a quadrilateral have the same number of vertices?
No because a triangle has 3 vertices whereas a quadrilateral has 4 vertices
Name a polygon that has less than 4 vertices?
A triangle has fewer than 4 vertices.
How many vertices on a triangle?
A triangle has three vertices. Each vertex is a point where two sides of the triangle meet. In total, a triangle is defined by these three vertices, along with its three sides.
What has 3 vertices?
A triangle has three vertices.
