Question

construct an isosceles triangle whise base is 4.8 cm and whose verticle angle is 80 degree. Also , Justify ur answer.....​

Answer 1

Hii..

Answer:

We have a verticle angle which measure is 80° , we have to find other two angles.

According to same base Angle of isosceles triangle, Angles adjecent with base are same.

Let the base angle = x

Now, According to Angle sum property,

Sum of all Angles = 180°

=> 80+ 2x = 180

=> 2x = 100

=> x = 100/2

=> x = 50

Steps of construction:

• Draw a line segment of 4.8 cm named AB.
• Draw an angle of 50° at point A on AB.
• Draw an another angle of 50° at point B on AB.
• Now, name the point of interaction C .
