Angle A and D are similar
Angle B and E are similar
Angle C and F are similar
So this means they have congruent angles, meaning whichever angles are similar the angles will also be similar.
So since angle A is 62 degrees, angle D is 62 degrees too.
Since angle E is 80 degrees, angle B has to be 80 degrees as well.
All triangles add up to 180 degrees, so to find the angle measure of angle C and F, do:
180-(62+80)
180-142
= 38 degrees
So angles C and F are 38 degrees
Conclusion:
angles A and D: 62 degrees
angles B and E: 80 degrees
angles C and F: 38 degrees
