Why is it impossible for a triangle to contain 180 degrees?
The opposite is in fact true; the total internal angles of all triangles is exactly 180 degrees.
Are all isosceles triangles with two 50 degrees and exactly one side of length 10cm congruent?
Yes, they are.
What phrase does SAS represent in geometry?
If any two sides of a triangle are equal in length to two sides of another triangle and the angles between each pair of sides have the same measure, then the two triangles are congruent. AKA the triangles are exactly the same size. (SAS stands for Side Angle Side.)
Which type of arc measures exactly 180?
An arc that measures exactly 180 degrees is called a semicircle. In a circle, a semicircle is formed when an arc spans half of the circumference, which corresponds to 180 degrees. Semicircles are important in geometry and trigonometry, often used in calculations involving angles and circles.
In hyperbolic geometry a triangle could potentially have degrees.?
In hyperbolic geometry, triangles have angles that sum to less than 180 degrees, which contrasts with Euclidean geometry where the sum is exactly 180 degrees. This means that while hyperbolic triangles can still have angle measurements in degrees, the total of those angle measures will always be less than 180. Consequently, the concept of "degrees" is applicable, but the properties of the triangles differ significantly from those in Euclidean space.
In non-Euclidean geometry triangles on a sphere have?
In non-Euclidean geometry, specifically on the surface of a sphere, triangles have angles that sum to more than 180 degrees. This is contrary to the properties of triangles in Euclidean geometry, where the angle sum is always exactly 180 degrees. Additionally, the shortest path between two points on a sphere is along a great circle, which further influences the characteristics of spherical triangles. As a result, the shapes and relationships within triangles on a sphere differ significantly from their flat counterparts.

What is a straight line in geometry?
an angle that measures exactly 180 degrees
When Compare and contrast Euclidean geometry and spherical geometry. Be sure to include these points 1. Describe the role of the Parallel Postulate in spherical geometry. 2. How are triangles differen?
Euclidean geometry is based on flat surfaces and includes the Parallel Postulate, which states that through a point not on a line, exactly one parallel line can be drawn. In contrast, spherical geometry operates on a curved surface where the concept of parallel lines does not exist; any two great circles (the equivalent of straight lines on a sphere) will intersect. In spherical geometry, triangles have angles that sum to more than 180 degrees, unlike in Euclidean geometry, where the angles of a triangle always sum to exactly 180 degrees. Thus, the fundamental properties and the behavior of lines and angles differ significantly between the two geometries.
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.
Do all triangles have square corners?
No, not all triangles have square corners. A triangle can have angles that are acute (less than 90 degrees), right (exactly 90 degrees), or obtuse (greater than 90 degrees). Only right triangles have one square corner, while acute and obtuse triangles do not have any square corners at all.
Why is it impossible for a triangle to contain 180 degrees?
The opposite is in fact true; the total internal angles of all triangles is exactly 180 degrees.
What are the types of traiangle?
There are several types of triangles classified by their sides and angles. By sides, a triangle can be classified as equilateral (all sides equal), isosceles (two sides equal), or scalene (all sides different). By angles, triangles can be acute (all angles less than 90 degrees), right (one angle exactly 90 degrees), or obtuse (one angle greater than 90 degrees). These classifications help in understanding their properties and applications in geometry.
Are all isosceles triangles with two 50 degrees and exactly one side of length 10cm congruent?
Yes, they are.
What do you look for if you want to classify a triangle?
Classifying triangles is a great skill to know.Acute Triangles: These are triangles with measures lessthan 90 degrees.Obtuse Triangles: Any triangle with measures greater than 90 Degrees.Right Triangle: Any triangle with a Right Angle (exactly 90 degrees)
What type of triangle can have one right angle?
A triangle that has one right angle is called a right triangle. In a right triangle, one of the interior angles measures exactly 90 degrees, while the other two angles are acute, adding up to 90 degrees. Right triangles are fundamental in trigonometry and are often used in various applications, including geometry and physics.
