Draw a Delta ABC. 1.Bisect angleB and ...

Draw a `Delta ABC`.
1.Bisect `angleB` and name the point of intersection of AC and the angle bisecto as D.
2. Mesure the sides.
AB= `square` cm , BC = `square` cm,
AD = `square` cm, DC = `square` cm
3.Find rations `(AB)/(BC) and (AD)/(DC)`.
4.You will find thaat both the rations are almost equal.
6.Bisect remaining angles of the triangle and find the ration as above. Verify that the rations are equal.

Text Solution

Verified by Experts

The correct Answer is:
`therefore (AB)/(BC) = (AD)/(DC)`
