There are normally three rectangular faces and so their angles are all right angles. But there are no restrictions on the angles of the triangular faces other than that they sum to 180 degrees.
If all of the angles add to 180 degrees the figure is a triangle. * * * * * That is if they form a plane figure. Angles that add to 1890 degrees are called supplementary angles.
Sum of angles in a triangle is 180
All The Angles On A Straight Line Add Up To 180 Degrees.
Coz all 3 angles have to add to 180. If you add 2 90's you get 180 so there are no angles left for the third corner.
they all add up to 180 degrees. so if you are given 2 of the angles then you add them together. subtract them from 180 and thats your answer
Interior angles of all triangles add up to 180 degrees.
The 3 interior angles of a triangle add up to 180 degrees
