Experimentally varify triangle

Materials Required:

Cardboard

Coloured glazed papers

White paper

Tracing paper

Scissors

Geometry box

Sketch pens

Adhesive

Prerequisite Knowledge

Concept of triangle and its properties.

Theory

For concept of triangle and its properties refer to

Procedure

Take a cardboard of suitable size and by using adhesive, paste a white paper on it.

Cut out a ΔABC from a glazed paper and by using adhesive, paste it on cardboard,

Verify that in a Triangle, Longer Side has the Greater Angle 1

Measure the lengths of all the three sides of ΔABC and identify that which of them is longest.

All the three angles of a triangle are to be marked,

Verify that in a Triangle, Longer Side has the Greater Angle 2

Using a tracing paper, make the cut out of the angle opposite to the longest side SC, i.e. ∠A.

Verify that in a Triangle, Longer Side has the Greater Angle 3

Compare the cut out of the angle with remaining angles.

Verify that in a Triangle, Longer Side has the Greater Angle 4

Demonstration

We came to know that ∠A > ∠B and ∠A > ∠C , BC > AC,

So, we get since ∠A > ∠B

Also, BC > AB, since ∠A > ∠C

Thus, we observe that the angle belongs to longer side is greater than the angle opposite to other side.

Observation

Length of side AB = ……….. , Length of side BC = ………. , Length of side CA = ………… ,

Measure of the angle opposite to the longest side = …………. ,

Measure of the other two angles = …………… and ………. ,

The angle opposite to the …………. side ……….. is than either of the other two angles.

Result

We have verified experimentally that in a triangle

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
