Prove triangle=180°

1.	Prove triangle=180°
Answer» Let the sides of triangle be x As we know triangle have 3 sidesHence, sides of triangle be=3xSum of three sides of triangle=180°So,3x=180°x=180/3x=60°Hence each side of triangle is 60+60+60Which is 180Hence proved..... Sum of three angles is 180 degree If you understand with this answer like please TrianglePQR with angle <1,<2and <3.Then<1+<2+<3=180 degree<1+<4+<5=180 degree(linear pair).<1+<2+<3=180degree(from(1)and (2)
