What does classifying triangles mean?
Some triangles can be classified by only term, and some triangles fall into two overlapping, non-mutually-exclusive categories.
What does mean for two triangles to be congruent?
That they are both identical in size and angles
Is there an SAS postulate for similarity of two triangles also just as you have one for congruency of triangles?
YesFor two triangles to be congruent, their corresponding sides must be of equal length. But for triangles to be similar, they must only have equal angles. For there to be a SAS postulate for similarity, the two corresponding sides would have to be proportionate, not equal. If they were equal, the triangles would be congruent.So, an SAS postulate for similar triangles would mean that two of the sides of the smaller triangle are, for example, half the two corresponding sides of the other triangle. If also the corresponding included angles are equal, then the two triangles would be similar triangles.APEX: similar
How many number of triangles in a quadrilateral?
Two triangles
What are two congruent triangles?
They are two triangles whose corresponding sides and angles are the same.
