Question

Contract a triangle ABC with measure AB=5cm,BC=4.2cm,AC=6.5.measure the angles. Write relationship between sides and angles

Answer 1

i dont know the relation

Answer 2

According the question we have to construct a Δ ABC .

where AB=5cm,

BC=4.2cm,

AC=6.5.

And also measure the angles.

Let,s start :-

• First we draw a line which is sufficiently prolonged the usage of ruler.
• In this step we will draw points 'B' and 'C' on it such that BC = 4.2cm

• Taking 'B' as Center and radius 5cm , we will draw an arc.

• Here we will consider 'C' as Center and radius 6.5cm , and will draw  arc reducing the previous arc at 'A'

• This is the last step, will join BA and CA.

∴  ABC is the required triangle.

"Angle opposite to greater side is more than the angle opposite lesser side" . and measures of angles are :-

∠A = 88° ,

∠C = 48° ,

∠B = 44°.

Ans :- "Angle opposite to greater side is more than the angle opposite lesser side" . ∠A = 88° , ∠C = 48° ,∠B = 44°.
