Question 4

Q4) Construct a triangle XYZ, in which XY = YZ = ZX = 4.5 cm. Draw all its lines of symmetry.

Solution

Transcript

Solution:

Draw line XY = 4.5 cm

With X as a center and radius 4.5 cm draw an arc at Z.

With Y as a center and radius 4.5 cm draw an arc which cuts the previous arc at Z.

Join XZ and YZ.

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