Answer 1

Answer:

Yes, Triangle is Isosceles

Step-by-step explanation:

By Linear pair, angle ACB is 50 degree

Therefore by angle sum property

80+50+ angle ABC=180

130+angle ABC =180

angle ABC=180 - 130 =50 degree

So the opposite sides AB and AC are equal

Therefore triangle ABC is an isosceles triangle

Answer 2

Angle ACD = 130⁰

so angle ACB =

180⁰-130⁰=50⁰ANSWER

Now, A + B+ C = 180⁰

80⁰+ B + 50⁰= 180⁰

130⁰+ B= 180⁰

B= 180⁰ - 130⁰

B= 50⁰ ANSWER

Angle ABC is an isosceles triangle because angle B=C= 50⁰ and angle A= 80⁰

because in an isosceles triangle two angles are equal and one is different
