Class –VII Mathematics (Ex. 10.2)

###### Question 1.Construct {tex}\Delta {/tex}XYZ in which XY = 4.5 cm, YZ = 5 cm and ZX = 6 cm.

To construct: {tex}\Delta {/tex}XYZ, where XY = 4.5 cm, YZ = 5 cm and ZX = 6 cm. Steps of construction:

(a) Draw a line segment YZ = 5 cm.

(b) Taking Z as centre and radius 6 cm, draw an arc.

(c) Similarly, taking Y as centre and radius 4.5 cm, draw another arc which intersects first arc at point X.

(d) Join XY and XZ.

It is the required {tex}\Delta {/tex}XYZ.

###### Question 2.Construct an equilateral triangle of side 5.5 cm.

To construct: A {tex}\Delta {/tex}ABC where AB = BC = CA = 5.5 cm Steps of construction:

(a) Draw a line segment BC = 5.5 cm

(b) Taking points B and C as centers and radius 5.5 cm, draw arcs which intersect at point A.

(c) Join AB and AC.

It is the required {tex}\Delta {/tex}ABC.

###### Question 4.Construct {tex}\Delta {/tex}ABC such that AB = 2.5 cm, BC = 6 cm and AC = 6.5 cm. Measure {tex}\angle {/tex}B.

To construct :{tex}\Delta {/tex}ABC in which AB = 2.5 cm, BC = 6 cm and AC = 6.5 cm. Steps of construction:

(a) Draw a line segment BC = 6 cm.

(b) Taking B as centre and radius 2.5 cm, draw an arc.

(c) Similarly, taking C as centre and radius 6.5 cm, draw another arc which intersects first arc at point A.

(d) Join AB and AC.

(e) Measure angle B with the help of protractor.

It is the required {tex}\Delta {/tex}ABC where {tex}\angle {/tex}B = {tex}80^\circ .{/tex}
