Introduction - We are familiar with plane figures bounded by straight line segments as sides. They are known as Polygons . Polygon is a word of Greek origin. It means figure with many angles implying many sides. Squares, rectangles and other four-sided geometric figures formed b..
Pythagoras' Theorem
Pythagoras' Theorem - In a right angled triangle, the square on the hypotenuse is equal to the sum of the squares on the sides containing the right angle. ABC is a triangle with BAC = 90 o . BC 2 = AB 2 + AC 2 . On AB, BC and CA as sides, describe square..

The four bond pairs are distributed in a planar distribution. The two lone pairs are in a direction at right angles to this plane. This gives a square planar shape to such molecules. Examples include ICl - 4 , XeF 4 and [Ni(CN) 4 ] 2 - ...

very helpful of a complex problem, oh my god I would have never completed this problem with out the tutor. Tutor vista thank u so much.
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
Their whiteboard is great. Online tutoring from this site is as good as like face to face tutoring and the great thing is I dont have to spend a lot.
Encouraging resource, great material to help students with studies. Really helpful... - Paul
