Question

if the exterior angle of an isosceles triangle is 12 degree and its interior opposite angles are equal ,what is the value of each interior opposite angle? ​

Answer 1

Given :-

• Exterior angle = 12°
• And interior opposite angles are equal

To find:-

• The both interior opposite angles

Solution :-

Let one interior angle be x . Automatically the both angles also will be x since , they are equal

Using Exterior angle property.

Exterior angle property :- Exterior angle property is defined as "exterior angle equal to sum of two interior opposite angles .

Similarly , here in other form

→ 12° = x° + x°

→ 2x° = 12°

→ x = 12/2

→ x = 6°

Hence , both interior opposite angles equal to = 6°

Answer 2

Both the angles are 6° each.

In the exterior angle property, the exterior angle is equal to the sum of two interior opposite angles....
