An isosceles triangle has an angle that measures 80°. What measures are possible for the other two angles? Choose all that apply.

Answer 1

50 and 50

or

80 and 20

the total sum of all 3 angles for any triangle is 180 degrees

180-80 = 100 degrees for the other two angles

either 100/2 = 50 for each of the other two

or

180-80-80 = 20, with 80 and 20 as the other two angles

80+80+20 = 180

or

80+50+50 = 180
