Question

Activity: Draw A ABC of any measure on a card-sheet and cut it out. Place it on a card-sheet. Make a copy of it by drawing its border. Name it as A A,B,C, Now slide the A ABC which is the cut out of a triangle to some distance and make one more copy of it. Name it A A,B,C, Then rotate the cut out of triangle ABC a little, as shown in the figure, and make another copy of it. Name the copy as A A,B,C.. Then flip the triangle ABC, place it on another card-sheet and make a new copy of it. Name this copy as A A,B,C, Have you noticed that each of A A,B,C,, A A,B,C,, A A,B,C, and A ABC, is congruent with A ABC ? Because each of them fits exactly with A ABC. Let us verify for A A,B,C,. If we place ZA upon ZA,, ZB upon ZB, and ZC upon ZC, then only they will fit each other and we can say that A ABC = A A,B,C We also have AB = A,B, , BC = B,C,, CA= CA, Note that, while examining the congruence of two triangles, we have to write their angles and sides in a specific order, that is with a specific one-to-one correspondence If A ABC = A PQR, then we get the following six equations : ZA= ZP, ZB = ZQ, ZC = ZR.... (I) and AB =PQ, BC = QR, CAERP.... (II) This means, with a one-to-one correspondence between the angles and the sides of two triangles, we get three pairs of congruent angles and three pairs of congruent sides. 3 3 answer in shalla. com​
