You are trying to work out missing angles about certain points of angles in a triangle?

to find missing angles you are dealing with complementry and suplementry angles. Suplementry angles add up to 180 degrees so you must subtract what given angle you have from 180 and you come up with youre missing angle. This rule also gos for complementry but the angles must add up to 90 degrees

What is the sum of angles of a triangle?
The sum of the angles in a planar triangle, i.e., a triangle where all of the points of the triangle lie in a single plane, is 180 degrees.
What is the least amount angles a triangle can have?
the answer is three i say that because triangles are pointy there are three points an there all closed so its 3 angles
How many components a triangle has?
A triangle has three components - three sides, three angles, and three vertices. The sides are the line segments that connect the vertices, the angles are the measurements between these sides, and the vertices are the points where the sides intersect.
How many intersecting lines does a triangle have?
3 intersecting lines, because none of the three points are right angles.
What is relationship between exterior angles and opposite interior angles of a triangle?
The exterior angle of a triangle is equal to the sum of the two opposite interior angles. So if a triangle had points A, B and C: The exterior angle at B would equal the sum of interior angles at A and C. Similarly, the exterior angle at C would equal the sum of interior angles at A and B And the the exterior angle at A would equal the sum of interior angles at C and B.
What are the 3 angles in a triangle?
They are the three points at which the sides of a triangle meet - in pairs.
What does the angles about any point of a triangle add up to?
The points in a triangle has to be 180 degrees to be a triangle.
What is the sum of angles of a triangle?
The sum of the angles in a planar triangle, i.e., a triangle where all of the points of the triangle lie in a single plane, is 180 degrees.
What are the angles in a triangle?
all the points. also they should always add up to 180. as if you think about it a triangle is half a square/rectangle.
Why do the interior Angles of a 5 point star always equal 180 degrees?
Funny thing is, I was just asked to do this in my geometry class. And I figured out this method that my teacher had never heard of. Ok, let's say that the five angles are named angles A, B , C, D, and E, going aound counter clockwise. Points ACD form a trinalge, and everybody knows that a triangle forms 180 degrees. But, i problem, you are missing two angles that would complete the triangle. While thinking on this problem last week in my 9th grade geometry class, I realized that the sum of the two missing angles is equivilant to the sum of angles B and E, the two "left over" angles, unused in the triangle. Thus, the sum of all five angles MUST add up to 180 degrees. I went a little farther to figure out why exactly the sum of the two "missing" angles is equal to the sum of angles B and E all the time, no matter how you manipulate it. Let's call the point formed going in towards the center of the triangle formed by angles C and D point F. There are two triangles formed here, triangle FCD and triangle BEF. The foint shared creates two vertical angles, meaning they are equal. Then the "left over" amount of degrees in both triangles has to be the same, proving that the sum of the two missing angles will be equal to the sum of angles B and E. There you go,, PLEASE do not copy this to use on a project. I will hear abput it and just, ...............................................

What is the point of a triangle called?
A triangle is a polygon and one of the basic shapes in geometry with three edges and three vertices. The points of edges of a triangle are known as angles, corners or vertices.

A triangle has three components - three sides, three angles, and three vertices. The sides are the line segments that connect the vertices, the angles are the measurements between these sides, and the vertices are the points where the sides intersect.

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.
Can the incenter and the circumcenter of a triangle ever be the same point?
Yes. The two points will be the same when it is a regular triangle (all 3 sides are the same length, all three angles are 60 degrees)
