Three interior angles of a triangle have a sum of?
Interior angles of a triangle have a sum of 180 degrees.
What do all the angles of a triangle add up to?
Sum of angles in a triangle is 180
Triangle with two 60 degree angles?
equilateral triangle (and so, if it is in Euclidean (plane) space, it has 3 angles all of which are 60°) otherwise (in Hyperbolic or Spherical space) it is an isosceles triangle.
What is the total interior angles for an equilateral triangle?
All triangles have a total of 180 degrees for interior angles in Euclidean plane geometry
Sum of measures of angles of a triangle to sum or measures or angles of a rectangle?
The sum of the internal angles of any triangle is 180 degrees. Any rectangle has four 90 degree internal angles, totalling 360 degrees.
What is the triangle angle sum theorem?
The sum of the interior angles of a triangle in euclidean geometry equal 180 degrees
What is the sum of the interior angles of a triangle in non-Euclidean geometry?
Any number you like.
Can the sum of the angles of a triangle exceed 180 degrees?
In basic Euclidean geometry no, the sum of the angles always equals 180 degrees exactly. In non-Euclidean geometry it can exceed 180 degrees.
Does an angle of an triangle sum up to 180 degrees?
The sum of the interior angles of a triangle always add up to 180 degrees. In Euclidean geometry
When do the angles in a triangle not add up to 180 degrees?
If the sum is not 180° you are not in Euclidean space.If the three angles of a triangle add up to more than 180° then you are in a spherical space, if the sum is less than 180° it is a hyperbolic space.The internal angles of a planar (Euclidean) triangle always add up to 180 degrees.
What is the sumof the measure of the three anglesin a triangle?
The sum of the three angles in any triangle is 180 degrees. In plane Euclidean geometry
How much is the sum of all the angles in a right triangle?
The sum of the angles in all triangles (right, isosceles, scalene, and equilateral) in the Euclidean plane is 180 degrees or pi.
How do you find the angle of triangle if their sum and difference is given?
In plane Euclidean geometry there are 3 angles in any triangle that add up to 180 degrees and if given 2 angles the sum of the 2 angles minus 180 will give the measure of the 3rd angle
Is it true that the sum of three angles of any triangle is 180 in non euclidean geometry?
No. Non-Euclidean geometries usually start with the axiom that Euclid's parallel postulate is not true. This postulate can be shown to be equivalent to the statement that the internal angles of a traingle sum to 180 degrees. Thus, non-Euclidean geometries are based on the proposition that is equivalent to saying that the angles do not add up to 180 degrees.
A triangle that measures 60 60 90 degrees is?
isosceles * * * * * In the Euclidean plane such a triangle could not exist, because the sum of its angles exceeds 180 degrees.
What are The measure of an exterior angle of a triangle is greater than the sum of the measures of the two opposite interior angles?
It is an indication of an error, or the fact that the triangle is not in the Euclidean plane but on a convex surface.
Do the angles in a triangle add up to 180?
Yes, in Euclidean space.If the sum is not 180° you are not in Euclidean space.If the three angles of a triangle add up to more than 180° then you are in a spherical space, if the sum is less than 180° it is a hyperbolic space.Example:Think of a triangle on the Earth with one corner at the North Pole, the other corners on the Equator 90° apart (say at 0° [west of Nigeria in Africa] the other at 90° W [West of Ecuador in South America]).Each of these angles is 90° so the sum is 270° -The surface area of the triangle is one eighth of the surface of the globe. But it is a triangle (on a sphere)!
