Question

One of the equal angles of an isosceles triangles is 50 degree . Find all the angles of this triangle.

Answer 1

Hey mate!

Here is your answer > >

First angle of isosceles triangle=50°

Second angle of isosceles triangle=50°

Let Third angle of isosceles triangle=x

According to angle sum property of triangle

x+50°+50°=180°

x+100°=180°

x=180°-100°

x=80°

Angles of the triangle are 50°,50°,80°

Hope it helps!

Answer 2

Given:

One of the equal angles of an isosceles triangle is 50 degree

To Find:

Find all the angles of triangles

Solution:

Let third angle be x  

Measure of each of equal angles =$50^{\circ}$

Angle sum property: The sum of all angles of triangle is 180°.

Using Property:

So, $50^{\circ}+50^{\circ}+x=180^{\circ}\\\Rightarrow 100^{\circ}+x=180^{\circ}\\\Rightarrow x = 180^{\circ}-100^{\circ}\\\Rightarrow x = 80^{\circ}$

Hence The angles of triangle are 50°,50° and 80°
