Parallelogram Theorem Proof 4:In square diagonals are equal and bisect perpendicularly
In this video we will learn how diagonals in square are equal and bisect each other perpendicularly
In this video, we learn how to apply Congruency Rule to solve Problems on Qudrilaterals. Use parallel lines concept and triangle congruence theorems to prove/solve problems on properties of parallelograms.
Reference book for the above video is
National Council of Educational Research and Training (NCERT) Book for Class 9 Subject: Maths
Parallelogram Theorem Proof 4:In a Square, diagonals are equal and bisect each other at right angles.
00:02 CBSE class 9 maths NCERT Solutions chapter 10 Quadrilaterals q4. Show that the diagonals of a square are equal and bisect each other at right angles.
02:30 Use SAS congruency rule
03:38 Use of rule Vertically opposite angles are equal.
04:05 Use parallel lines property:Alternate interior angles are equal
05:15 Apply CPCT (Corresponding Parts of Congruent Triangles))
