The interior angle sum of triangles and finding the missing angle in a triangle.

               Find the missing angles in triangles.

I will be teaching you today about finding the missing angle in triangle.

First of all you need to know that the sum of the angles in a triangle always add up to 180 degrees.

Most of the time they represent the missing number with with a letter such as x.

Bh represent base and height of a triangle.

First of all you add up the all ready given angles of the triangle then find the sum that's missing will be the angle.
