Quesiton : How many degrees total in a triangle?

Answer: 180

How many degrees total in a triangle? In geometry Euclidean space encompasses the two-dimensional Euclidean plane the three-dimensional space of Euclidean geometry and certain other spaces. It is named after the Ancient Greek mathematician Euclid of Alexandria. The term "Euclidean" distinguishes these spaces from other types of space… How can the answer be improved? Angles of a Triangle - Free Math Help How to Calculate the Area of a Triangle - Using Trigonometry How to Calculate the Area of a Triangle (with Cheat Sheets) How to Find the Angles of a Right Triangle | Sciencing Right Triangles | GMAT Free In a triangle the three interior angles always add to 180°: Try it yourself (drag the points): The exterior angles of a triangle are all the angles between one side of the triangle and the line you get by extending a neighboring side outside the bounds of the triangle. If you think about it you'll see that when you add any of the interior angles of a triangle to its neighboring exterior angle you always get 180 0 … Fri Oct 06 2006 00:00:00 GMT+0530 (IST) · Source(s): The sum of the interior angles of any triangle equals 180 degrees . I didn't know that the sum of the 3 interior angles in a triangle could be more or less than 180 degrees . By defintion it's 180 if you use the 360 degree circle. Engineers use a 400 gradian circle so for them a triangle has 200 gradians. Answer (1 of 5): In plain geometry there are a total of 180 degrees . However on a concave surface there will be less than 180 degrees . On a convex surface there will be more than 180 degrees . Only on a flat plain with there be 180 degrees . What you have now is two right triangles which by the above contain 360 degrees in total. But if you look at the two right angles that add up to 180 degrees so the other angles the angles of the original triangle add up to 360 - 180 = 180 degrees. Penny. Tue Feb 12 2019 00:00:00 GMT+0530 (IST) · All triangles have a total of 180 degrees. The internal angles of any triangle add up to 180 degrees. Therefore a RIGHT triangle's angle's added together equal 180 degrees. The Right Angle = 90 degrees + the other 2 angles total 90 degrees making the total number of degrees in a Right Angle Triangle = 180 degrees. 18 people found this useful. A triangle is a three-sided polygon where the sum of its interior angles equals 180 degrees . Some common formulas for triangles include perimeter the total sum of its individual side lengths; area one-half of the product of a triangle’s base and height; and angle calculations based on the Pythagorean Theorem.
