Question

Triangle ABC and Triangle DEF shown in the diagram below are similar.

In Triangle ABC, m In Triangle DEF, m
What's the measure of G? FInd the measures of all missing angles.

Answer 1

angle G= 135°

angle E = 45°

angle D = 64°

angle B= 45°

angle C = 71°

Step-by-step explanation: Since ∆ABC~∆DEF

therefore angle A~angle D

angle B~angle E and angle C ~angle F

angle G = 180°- angle

i.e. 180° - 45° = 135°

reason :sum of angles on a straight line is 180°
