AP State Syllabus AP Board 7th Class Maths Solutions<\/a> Chapter 8 Congruency of Triangles Ex 2 Textbook Questions and Answers.<\/p>\n

AP State Syllabus 7th Class Maths Solutions 8th Lesson Congruency of Triangles Exercise 2<\/h2>\n

\"AP<\/p>\n

Question 1.
\nWhat additional information do you need to conclude that the two triangles given here under are congruent using SAS rule?
\n\"AP
\nSolution:
\nWe need
\nHG = TS
\nHJ = TR<\/p>\n

\"AP<\/p>\n

Question 2.
\nThe map given below shows five different villages. Village M lies exactly halfway between the two pairs of villages A and B as well as and P and Q. What is the distance between village A and village P. (Hint: check if \u0394PAM \u2245 \u0394QBM)
\n\"AP
\nSolution:
\nGiven that
\nAM = MB
\nPM = MQ
\nalso \u2220PMA = \u2220QMB
\n\u2234 By S.A.S
\n\u0394PMA \u2245 \u0394QMB
\nNow PA = BQ
\n(\u2235 Corresponding parts of congruent triangles are equal)
\n\u2234 PA = 4 km
\ni.e., Distance between the villages
\nA and P is 4 km.<\/p>\n

\"AP<\/p>\n

Question 3.
\nLook at the pairs of triangles given below. Are they congruent ? If congruent write the corresponding parts.
\n\"AP
\n\"AP
\n\"AP
\n\"AP<\/p>\n

Solution:
\n\"AP
\nAB=ST
\nAC = SR (given)
\n\u2220A = \u2220S
\n\u2234 \u0394ABC \u2245 \u0394STR (S.A.S)
\nAlso \u2220A = \u2220S, \u2220B = \u2220T, \u2220C = \u2220R<\/p>\n

\"AP
\nFrom the figure,
\nFO = RO
\nOQ = OS
\n\u2220POQ = \u2220ROS
\n\u2234 \u0394POQ \u2245 \u0394ROS (SAS)
\nAlso \u2220P = \u2220R, \u2220Q = \u2220S, and PQ = RS<\/p>\n

\"AP<\/p>\n

\"AP
\nFrom the figure, IAPBoardSoIJ
\nWD = OR
\n\u2220W= \u2220R
\nWO = RD
\n\u2234 \u0394DWO \u2245 \u0394ORD
\nAlso \u2220EO = \u2220OE; \u2220WDO = \u2220ROD; \u2220WOD = \u2220RDO<\/p>\n

\"AP
\nHere the two triangles \u0394ABC and \u0394CDA are not congruent.<\/p>\n

Question 4.
\nWhich corresponding sides do we need to know to prove that the triangles are congruent using the SAS criterion?
\n\"AP
\nSolution:
\ni) We need to know that AB = QR.
\nii) We need to know that AD = AB.<\/p>\n","protected":false},"excerpt":{"rendered":"
