Question

construct angle xyz whose perimeter 8.4 cm and xy : yz : xy = 5: 7: 9​

Answer 1

XYZ is the required triangle and line of symmetries are shown in the figure.

Step-by-step explanation:

1. Draw line XY = 4.5 cm
2. With X as a center and radius 4.5 cm draw an arc at Z.
3. With Y as a center and radius 4.5 cm draw an arc which cuts the previous arc at Z.
4. Join XZ and YZ.
