NCERT Solutions for Class 8 Maths Chapter 4 Practical Geometry Exercise 4.5<\/h2>\n

Draw the following.<\/span><\/p>\n

Question 1.
\nThe square READ with RE = 5.1 cm.
\nSolution:
\n\"NCERT
\nSteps of construction:
\nI. Draw a line segment RE = 5.1 cm.
\nII. At E, draw \\(\\overrightarrow{\\mathrm{EX}}\\), such that \u2220REX = 90\u00b0.
\nIII. From \\(\\overrightarrow{\\mathrm{EX}}\\), cut-off \\(\\overrightarrow{\\mathrm{EA}}\\) = 5.1 cm.
\nIV. With centre at A, draw an arc above RE of radius = 5.1 cm.
\nV. With centre at R, and radius = 5.1 cm, draw another arc to intersect the previous arc at D.
\nVI. Join DA and DR. Thus, READ is the required square.<\/p>\n

\"NCERT<\/p>\n

Question 2.
\nA rhombus whose diagonals are 5.2 cm and 6.4 cm long.
\nSolution:
\n\"NCERT
\nNote: The diagonals of a rhombus bisect each other at right angles.
\nSteps of Construction:
\nI. Draw a line segment AC = 5.2 cm.
\nII. Draw \\(\\overrightarrow{\\mathrm{XY}}\\), the perpendicular bisector of AC.
\nIII. From XY, cut-off OD = \\(\\frac{1}{2}\\) \u00d7 (6.4 cm) = 3.2 cm.
\nIV. Similarly, cut-off OB = \\(\\frac{1}{2}\\) \u00d7 (6.4 cm) = 3.2 cm.
\nV. Join AD, DC, CB, and BA. Thus, ABCD is the required rhombus.<\/p>\n

Question 3.
\nA rectangle with adjacent sides of length 5 cm and 4 cm.
\nSolution:
\n\"NCERT
\nSteps of Construction:
\nI. Draw a line segment PQ = 5 cm
\nII. At Q draw \\(\\overrightarrow{\\mathrm{QX}}\\) such that \u2220PQX = 90\u00b0
\nIII. From \\(\\overrightarrow{\\mathrm{QX}}\\), cut-off QR = 4 cm.
\nIV. With centre R and radius = 5 cm draw an arc.
\nV. With centre P and radius = 4 cm draw an arc to intersect the previous arc at S.
\nVI. Join RQ and RS. Thus, PQRS is the required rectangle.<\/p>\n

\"NCERT<\/p>\n

Question 4.
\nA parallelogram OKAY where OK = 5.5 cm and KA = 4.2 cm. Is it unique?
\nSolution:
\n\"NCERT
\nSteps of Construction:
\nI. Draw a line segment OK = 5.5 cm.
\nII. At K, draw a ray \\(\\overrightarrow{\\mathrm{KX}}\\).
\nIII. From \\(\\overrightarrow{\\mathrm{KX}}\\), cut-off KA = 4.2 cm.
\nIV. With centre at A and radius = 5.5 cm draw an arc above OK.
\nV. With centre O and radius = 4.2 cm, draw another arc to intersect the previous arc at Y.
\nVI. Join OY and AY. Thus, OKAY is the required parallelogram.<\/p>\n","protected":false},"excerpt":{"rendered":"
