How many triangles are there in the given figure?
3, 5, 6 are geometrical figures divided into two parts.
2, 4, 9 are geometrical figures divided into four parts.
There are three line segments in the first figure and these three line segments are converted into a three-sided geometrical figure, i.e., a triangle. Similarly, six line segments would be converted into a hexagon.
As we know that the mirror image always be opposite the original image across the given line. It will become opposite to the given line .As shown in given below .
Therefore , option C is required answer .
On the basis of above given question , we have
The mirror image always be opposite the original image across the given line. It will become opposite to the given line .As shown in given below .
Hence , option D is required answer .
2, 5, 8 are all three-dimensional figures.
3, 6, 9 are all (two-dimensional) triangles.
