What is the difference between triangle and a triangular region?
In figure, $A, B, C$ and $D$ are four points, and no three points are collinear. $AC$ and $BD$ interest at $O.$ There are eight triangles that you can observe. Name all the triangles.
View full solution →Take three collinear points $A, B$ and $C$ on a page of your note book. Join $AB, BC$ and $CA.$ Is the figure a triangle? If not why$?$
View full solution →In figure $D$ is a point on side BC of a $\triangle\text{ABC}. AD $ is joined. Name all the triangles that you can observe in the figure. How many are they?
