Question

in an isosceles triangle DEF, DE = DF if measure of angle EDF = 76 degree than the measure of DEF=

Answer 1

Answer:

52 degree

Step-by-step explanation:

Given: DE=DF

angle EDF=76 degree

solve: sum of all the angles of triangle ia 180 degree

If DE= DF

then angle DEF= angle DFE

SO let's assume that

angle DEF=angle DFE= x

so

angle def+ angle dfe+ angle edf= 180 degree

x+x+76=180

2x+76=180

2x=104

x= 52

so the measure of the angle def is 52 degree
