Question

in figure 6,4 show that angle A+angle B+ angle C+angle D+angle E+angle F=360°

Answer 1

the diagram consists of two triangles namely AEC and BDF . According to angle sum property in triangles the sum of all the angles in a triangle is equal to 180 degrees. so the two triangles here which consists of angles A,B,C,D,E, and F makes up 360 degrees of 180° from each triangle. so, those two triangles makes the sum =360°.
