Summary
Enlargement or Dilatation If D PQR is the image of D ABC (Pre image) and K is the enlargement factor, If K = 1 the triangles are congruent. The ratio of their areas is K 2 (SAS similarity) If a pair of corresponding angles are equal and the sides i..

The symbol for similarity is '~', For the above case, D ABC is similar to D XYZ. (i) If two triangles are congruent, then they are similar. Its converse is not true. (ii) = a constant. Let the constant be equal to K. Then K is called enlargement factor (or the dilation factor/sc..

While the nervous system and endocrine system have their own features, they have a common method of communication. Both the systems release chemicals to communicate between cells. Together these two systems carry out a very complex process of maintaining a homeostatic (balanced) internal environme..

Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
This Tutor Vista is GREAT! loved this session, it helped me heaps.
