Question

One of the base angles of an isoceles triangle is 70° . Find the vertical angle of the triangle

Answer 1

Answer:

the other vertex angles are 70,70,40.By using angle sum property

Answer 2

Answer:

As two sides of an isoceles triangle are equal so, 2 angles will be equal.

let that angles be as x°

Therefore, by angle sum property..

70° + x° + x° = 180°

2x = 110°

x = 55°

These are the vertical angles..
