Karnataka Board Class 8 Maths Chapter 11 Congruency of Triangles Ex 11.2<\/h2>\n

Question 1.
\nIn the adjoining figure PQRS is a rectangle. Identify the congruent triangles formed by the diagonals.
\n\"KSEEB
\nAnswer:
\n\u0394 PSR \u2245 \u0394 PQR, \u0394 POQ \u2245 \u0394 SOR
\n\u0394 SPQ \u2245 \u0394 SRQ, \u0394 POS \u2245 \u0394 QOR<\/p>\n

Question 2.
\nIn the figure ABCD is a square. M, N, O & P are the midpoints of sides AB, BC, CD and DA respectively. Identify the congurent triangles.
\n\"KSEEB
\nAnswer:
\n\u0394 APM \u2245 \u0394 BMD \u2245 \u0394 CNO \u2245 \u0394 DOP<\/p>\n

Question 3.
\nIn a triangle ABC, AB = AC. Points G on AB and D on AC are such that AE = AD. Prove that triangles BCD and CBE are congruent.
\n\"KSEEB
\nAnswer:
\nIn the figure AB = AC (data)
\n\u2234\u2220ABC = \u2220ACB
\n[Base angles of an isosceles triangle]
\nAB = AC(data)
\nAE = AD(data)
\nAB – AE = AC – AD (Axiom 3)
\nBE = DC
\nIn \u0394 BCD and \u0394 CBE
\n\u2220BCD = \u2220EBC
\nBE = DC (Proved)
\nBC = BC (Common side)
\n\u2234 \u0394 BCD= \u0394 CBE [SAS postulate]<\/p>\n

Question 4.
\nIn the adjoining figure the sides BA and CA have been produced such that BA = AD and CA = AE prove that DE || BC (hint : use the concept of alternate angles.)
\n\"KSEEB
\nAnswer:
\n\u0394 AED and \u0394 ABC
\nAE = AC (data)
\nAD = AB (data)
\n\u2220EAD = \u2220BAC
\n[Vertically opposite angles]
\n\u2234 \u0394 AED = ABC
\n[SAS postulate]
\n\u2234 \u2220AED = \u2220ACB [Congruent triangle property]
\nBut these are alternate angles.
\n\u2234 DE || BC
\nConsequences of SAS postulate.<\/p>\n","protected":false},"excerpt":{"rendered":"
