Cut out any 4 sided straight lined shape and the 4 interior angles will always add up to 360 degrees.
first we draw a triangle than we mark3angle of triangle. now think that which no. comes in all 3 angle of triangle that equals to 180 degrees because the sum of 3angles are 180 degr ees.
you could do a model showing the angle of elevation and angle of depression of a building
You can use pythagoras working model
clinometer
no

A simple working model can be as follows: Take 2 hollow tubes, the ones which can be used as pipelines for delivering water. Place them against a wall, both at an equal angle from the perpendicular to the wall. Place a alarm clock at the end of one of the tubes and try to listen through the second tube. You will see that you can hear the sound of the alarm quite clearly. This model shows that the angle of incidence of sound on a surface is equal to the angle of reflection of sound bouncing back from the surface.

There are a few ways to make an English working model. The exact model details depend on the type of English working model you want.
You can model a landslide with nothing more than dry sand and a dinner plate. Pour a pile of sand on the plate and notice that the angle of the sides of the pile are stable. Tip the plate slightly and the sand will slump off to try to re-establish that stable angle.
