Question

triangle ABC is isoscles with ab = ac if angle A = 80 degree what is the measure of angle C​

Answer 1

Answer:

plz check and let me know if the answer is helpful to you

Answer 2

Answer:

We know that opposite angles of an isosceles triangle are equal

If ab=ac

the opposite angles are equal

Let the angles be "x"

$\large{x+x+80=180(angle\:sum\:property}$

$\large{2x+80=180}$

$\large{2x=180-80}$

$\large{2x=100}$

$\large{x=50}$

❤So the measure of angle C and A is "50degree"✔
