All of the angles in a triangle add up to 180, so if one angel was 34, and another angle was 67, than the mystery angle would be 79. I got that because 180-(a+b)=c. 34 is a, and 67 is b.
if the triangle has one right angle in it
right angle!
At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle.
By using Pythagoras' theorem for a right angle triangle.
It is the longest side of a right angle triangle.
You can find the angle of a triangle within a circle segment using the circle theorems.
The 90 degree angle in a right angle triangle is opposite its hypotenuse.
You cannot find any angle, or either of the other two sides, in a non-right triangle, when given only one side.
if the triangle has one right angle in it
if the angle of a triangle are in the ratio 7:11:18,find the angle
It has a 90 degree angle..
right angle!
At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle.
