Construct a DeltaABC in which AB = 4 cm,...

Construct a `DeltaABC` in which AB = 4 cm, BC = 5.2 cm and CA = 4.5 cm.

Text Solution

Verified by Experts

Steps of construction :
1. Draw BC = 5.2 cm.
2. With B as centre and radius 4 cm, draw an arc.
3. With C as centre and radius 4.5 cm, draw another arc which cuts the first arc at A.
3. Join AB and AC.
`therefore DeltaABC` is the required triangle.
