Question

Innovative math project models for class 10 cbse

Answer 1

Property1-Corresponding angles are congruent (same measure)

Property2-Corresponding sides are all in the same proportion

So, I made a single standing triangle on a wooden board with just 3 pieces of logs with the help of a carpenter nearby.

2 sides were stick such that they form 2 adjacent sides of a triangle and the 3rd side was free to make different triangles from the same base model and show those above 2 properties.

Then I put some nails on the logs such that each nail on one log have the corresponding nail on another log such that if I put the 3rd free log on the nails it forms the 3rd side. and I can lift it and put it on another pair of nails.

Thus 1st property can be evidently seen. Also at the same time when I put the log on different pairs of nails, the different triangles thus formed will have the same proportions of sides as well.
