Is a right triangle always 180 degrees?
The three interior angles of a triangle will always have a sum of 180°.
Can a triangle not have 180 degrees?
Yes. The interior angles of a triangle add to 180 degrees only if the triangle is Euclidean, that is, on a flat plane. If the triangle is on a sphere or other convex surface, then the sum of the angles is more than 180 degrees. For example in the triangle below, each angle is 90 degrees so the total is 270 degrees.
Does the 180 rule apply to all triangles?
The sum of the interior angle measures of a triangle always adds up to 180°.
What is the 30 60 90 triangle rule?
The 30-60-90 triangle rule is for finding the the lengths of two sides when one side is given. The shorter side is opposite the 30 degree angle, the longer side is opposite the 60 degree angle, and the hypotenuse is opposite the 90 degree angle.
Is a right triangle 45 degrees?
