\n\"NCERT
\nSolution:
\n\"NCERT<\/p>\n

Question 3.
\nDiagonals AC and BD of a trape\u2220ium ABCD with AB || DC intersect each other at the point O. Using a similarity criterion for two triangles, show that \\(\\frac { OA }{ OC }\\) = \\(\\frac { OB }{ OD }\\)
\nSolution:
\n\"NCERT<\/p>\n

Question 4.
\nIn the adjoining figure, \\(\\frac { QR }{ QS }\\) = \\(\\frac { QT }{ PR }\\) and \u22201 = \u22202 show that \u2206PQS ~ \u2206TQR.
\n\"NCERT
\nSolution:
\n\"NCERT<\/p>\n

Question 5.
\nS and T are points on sides PR and QR of \u2206PQR such that \u2220P = \u2220RTS. Show that \u2206RPQ ~ \u2206RTS.
\nSolution:
\n\"NCERT<\/p>\n

Question 6.
\nIn the given figure, if \u2206ABE \u2245 \u2206ACD, show that \u2206ADE ~ \u2206ABC.
\n\"NCERT
\nSolution:
\n\"NCERT<\/p>\n

Question 7.
\nIn the given figure, altitudes AD and CE of \u2206ABC intersect each other at the point P. Show that:
\n(i) \u2206AEP ~ \u2206CDP
\n(ii) \u2206ABD ~ \u2206CBE
\n(iii) \u2206AEP ~ \u2206ADB
\n(iv) \u2206PDC ~ \u2206BEC
\nSolution:
\n\"NCERT<\/p>\n

Question 8.
\nE is a point on the side AD produced of a parallelogram ABCD and BE intersects CD at F. Show that \u2206ABE ~ \u2206CFB.
\nSolution:
\nGiven: ABCD is a parallelogram, whose side AD is produced to E. BE is joined which intersects CD at F.
\n\"NCERT
\nTO Prove: \u2206ABE ~ \u2206CFB
\nProof: In \u2206ABE and \u2206CFB
\n\u2220A = \u2220C [opposite angles of a parallelogram are equal]
\n\u2220AEB = \u2220EBC [alternate angle]
\nThus, by AA-similarity criterion
\n\u2206ABE ~ \u2206CFB
\nHence Proved.<\/p>\n

Question 9.
\nIn the given figure, ABC and AMP are two right triangles, right angled at B and M respectively. Prove that:
\n\"NCERT
\n(i) \u2206ABC ~ \u2206AMP
\n(ii) \\(\\frac { CA }{ PA }\\) = \\(\\frac { BC }{ MP }\\)
\nSolution:
\n\"NCERT<\/p>\n

Question 10.
\nCD and GH are respectively the bisectors of \u2220ACB and \u2220EGF such that D and H lie on sides AB and FE of \u2206ABC and \u2206EFG respectively. If \u2206ABC ~ \u2206FEG, show that
\nSolution:
\n\"NCERT
\n\"Class<\/p>\n

Question 11.
\nIn the given figure, E is a point on side CB produced of an isosceles triangle ABC with AB = AC. If AD \u22a5 BC and EF \u22a5 AC, prove that \u2206ABD ~ \u2206ECF.
\n\"NCERT
\nSolution:
\n\"NCERT<\/p>\n

Question 12.
\nSides AB and BC and median AD of a triangle ABC are respectively proportional to sides PQ and QR and median PM of \u2206PQR (see in given figure). Show that \u2206ABC ~ \u2206bPQR.
\n\"NCERT
\nSolution:
\n\"NCERT<\/p>\n

Question 13.
\nD is a point on the side BC of a triangle ABC, such that \u2220ADC = \u2220BAC. Show that CA\u00b2 = CB.CD.
\nSolution:
\n\"NCERT<\/p>\n

Question 14.
\nSides AB and AC and median AD of a triangle ABC are respectively proportional to sides PQ and PR and median PM of another triangle PQR. Show that \u2206ABC ~ \u2206PQR.
\nSolution:
\n\"NCERT<\/p>\n

Question 15.
\nA vertical pole of length 6 m casts a shadow 4 m long on the ground and at the same time a tower casts a shadow 28 m long. Find the height of the tower.
\nSolution:
\n\"NCERT
\nDE is a vertical pole of length = 6 m
\nLength of its shadow = 4 m
\nLet height of tower AB = h m
\nLength of its shadow = 28 m
\nIn \u2206ABC and \u2206DEC,
\n\u2220ABC = \u2220DEC [Each 90\u00b0]
\n\u2220C = \u2220C [Common]
\n\u2206ABC ~ \u2206DEC [AA]
\n\\(\\frac { AB }{ DE }\\) = \\(\\frac { 6 }{ x }\\) = \\(\\frac { 4 }{ 28 }\\)
\n\u21d2 x = 42 cm.<\/p>\n

Question 16.
\nIf AD and PM are medians of triangles ABC and PQR respectively, where \u2206ABC ~ \u2206PQR Prove that\u00a0 \\(\\frac { AB }{ PQ }\\) = \\(\\frac { AD }{ PM }\\)
