Question

in an isosceles triangle ABC if angle A equal to 70 degree find rest of the triangle​

Answer 1

Answer:

70,40 or 55,55

Step-by-step explanation:

when AB=BC

then, rest of the angle 70,40

when AB=AC

then rest of the angle 55,55...

Answer 2

Answer:

- in an isosceles triangle measure of two two lines and measure of two angles are equal.

- Sum. of all interior angles in a triangle is 180°.

Step-by-step explanation:

hence angle A = 70° which means another angle which is angle B will also be equal to 70°.

angle C = 180° - (70° + 70°)

180° - 140°

= 40°

hence the measure of the angles are-

A = 70°

A = 70°B = 70°

A = 70°B = 70°C = 40°

hope this helps.

have a great day.
