Question

Show that the sum of three angle of triangle is 360°

Answer 1

HEY FRIEND......
________________

HERE IS THE ANSWER TO YOUR QUESTION......
____________________

First cut 2 triangles of same length with the help of a ruler and a pencil.Then take a compass with a pencil fitted on it.Keep the needle point of the compass at the vertex of the triangle and draw an arc. Repeat the same on every vertex ie all the four vertex on both the triangles.Keep one triangle aside and cut the arc made on every vertex of the first side. Then u will get all the angle of the triangle.Then place all the cut out of arc or u can say the angles of the triangle one after another so that all the vertex of the triangle meet at the same point. After doing this u will notice that the when you have joined all the angles of the triangle as mentioned above,a circle is formed. And we know that a full circle means 360° because a protector which we use to measure any angle has degree upto 180 and when we keep 2 protector as if it make a circle then it's measure will be 180°+180°=360°.Hence it is proved that the sum of all the angles of a triangle is 360°.

Answer 2

in finger we draw a line pQ || RS

so angle

1 = 2 & 3 = 4 .....(1)

but angle

1 + 5 + 4 = 180°

from equation (1) we can say that angle

2 + 4 + 5 = 180°

and these angle are of a triangle...
