## NCERT Solutions for Class 7 Maths Practical Geometry

###### Question 1.Construct {tex}\Delta {/tex}DEF such that DE = 5 cm, DF = 3 cm and {tex}m\angle {/tex}EDF = {tex}{90^ \circ }.{/tex}

To construct: {tex}\Delta {/tex}DEF where DE = 5 cm, DF = 3 cm and {tex}m\angle {/tex}EDF = {tex}{90^ \circ }.{/tex}

Steps of construction:

(a) Draw a line segment DF = 3 cm.

(b) At point D, draw an angle of {tex}{90^ \circ }{/tex} with the help of compass i.e., {tex}\angle {/tex}XDF = {tex}{90^ \circ }{/tex}.

(c) Taking D as centre, draw an arc of radius 5 cm, which cuts DX at the point E.

(d) Join EF.

It is the required right angled triangle DEF.

###### Question 2.Construct an isosceles triangle in which the lengths of each of its equal sides is 6.5 cm and the angle between them is {tex}110^\circ .{/tex}

To construct: An isosceles triangle PQR where PQ = RQ = 6.5 cm and {tex}\angle {/tex}Q = {tex}110^\circ .{/tex}

Steps of construction:

(a) Draw a line segment QR = 6.5 cm.

(b) At point Q, draw an angle of {tex}110^\circ {/tex} with the

help of protractor, i.e., {tex}\angle {/tex}YQR = {tex}110^\circ .{/tex}

(d) Taking Q as centre, draw an arc with radius

1. cm, which cuts QY at point P. 110{tex}^\circ {/tex}

(e) Join PR

It is the required isosceles triangle PQR.

###### Question 3.Construct {tex}\Delta {/tex}ABC with BC = 7.5 cm, AC = 5 cm and {tex}m\angle {/tex}C = {tex}{60^ \circ }.{/tex}

To construct: {tex}\Delta {/tex}ABC where BC = 7.5 cm, AC = 5 cm and {tex}m\angle {/tex}C = {tex}{60^ \circ }.{/tex}

###### Steps of construction:

(a) Draw a line segment BC = 7.5 cm.

(b) At point C, draw an angle of {tex}{60^ \circ }{/tex} with the help of protractor, i.e., {tex}\angle {/tex}XCB = {tex}{60^ \circ }.{/tex}

(c) Taking C as centre and radius 5 cm, draw an arc, which cuts XC at the point A.

(d) Join AB

It is the required triangle ABC.
