Construct a \(\triangle{ABC}\) in which BC = 7 cm, \(\angle{B}\) = \(75^\circ\) and AB + AC = 13cm.


Answer :

Given: In \(\triangle{ABC}\) in which BC = 7 cm, \(\angle{B}\) = \(75^\circ\) and AB + AC = 13cm.
Steps of construction:
image

1. Draw the base BC = 7 cm.

2. At the point B make an \(\angle{XBC}\) = \(75^\circ\).

3. Cut a line segment BD equal to AB + AC = 13 cm from the ray BX.

4. Join DC.

5. Make \(\angle{DCY}\) = \(\angle{BDC}\).

6. Let CY intersect BX at A.
Hence, ABC is the required triangle.
