Since the sum of all angles in any triangle is equal to 180o , so there can be only one right angle if all other angles are to be greater than zero.

The sum of the three angles of any triangle is equal to 180 degrees.

F. Smarandache (1969) has established geometrical spaces such that some (well-known) “axiom” is false in at least two different ways, or is false and also sometimes true. Such an axiom is said to be $s$-denied for short.

A triangle that has one right angle is called a right triangle. A triangle that has one obtuse angle is called an obtuse triangle. When a triangle has three congruent sides, we call the triangle an equilateral triangle.

All the angles in a triangle can never be less than 60 nor greater than 60. However all the angles can be acute ,whether only two of them.

In a Euclidean space, the sum of angles of a triangle equals the straight angle (180 degrees, π radians, two right angles, or a half-turn). A triangle has three angles, one at each vertex, bounded by a pair of adjacent sides.

An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.

The interior angles of a triangle are the three angles on the inside of a triangle. These three angles always sum to 180 degrees.

A triangle’s angles add up to 180 degrees because one exterior angle is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the third angle to make a 180 angle.

Angles around a point add up to 360°.

An exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of exterior angle and interior angle is equal to 180 degrees.

The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.

Summed, the exterior angles equal 360 degreEs. A special rule exists for regular polygons: because they are equiangular, the exterior angles are also congruent, so the measure of any given exterior angle is 360/n degrees.

The sum of the exterior angles of a triangle and any polygon is 360 degrees. The remote angles are the two angles in a triangle that are not adjacent angles to a specific exterior angle. The sum of the remote interior angles is equal to the non-adjacent exterior angle.

The sum of exterior angles is 360°. The exterior and interior angles add up to 180° (notice the line they sit on in the diagram). The interior angle is 180° − 72° = 108° .

In a triangle, the angles add up to 180°. In a rectangle, the angles add up to 360°.

Turn the third triangle upside down and slot it between the other two on the line. The angles in the triangle you drew all add up to 180°. Remember, all angles on a straight line add up to 180°.

360 is just an arbitrary number to represent an entire arc, while there are infinitely many smaller arcs that can be represented by fewer degrees. All 2 dimensional polygons with more than 3 sides have angles that add up to 360 degrees. This is 100% incorrect. The interior angles of a pentagon add up to 540 degrees.

Exterior angles of a polygon have several unique properties. The sum of exterior angles in a polygon is always equal to 360 degrees. Therefore, for all equiangular polygons, the measure of one exterior angle is equal to 360 divided by the number of sides in the polygon.

Why Is A Full Circle 360 Degrees, Instead Of Something More Convenient, Like 100? A full circle is 360 degrees because the Babylonians used the sexagesimal system. It also represents the number of days a year and also because 360 is highly composite.

The precise statement of the conjecture is: Proof: This follows directly from the Quadrilateral Sum Conjecture which says that the sum of angles in any convex quadrilateral is equal to 360 degrees. Since a rectangle has four angles of equal measure, the measure of each must be 360/4, or 90 degrees.
