Theorem#12.1.4 - Class 9th | ptbb | Line bisector

🔹 Theorem: A theorem is a statement that can be demonstrated to be true by accepted mathematical operations and arguments. In general, a theorem is an embodiment of some general principle that makes it part of a large theory. The process of showing a theorem to be correct is called a proof. • Angle Bisector: (∠) Angle bisector is the ray which divides an angle into two equal parts. • Line segment (᭸) A part of a line 'l' distinguished or separated by distinct points P and Q of 'l' is said to form a line segment of 'l' . • Ray (→) A ray has one end point. • Line (⬌) Line has no end point. • Right bisector of a line segment : A line 'l' is called a the right bisector of a line segment if 'l' is perpendicular to the line segment and passes through its midpoint. • Bisection: Bi mean "two" & section mean "parts". Therefore, bisection means to divide into two equal parts. • Triangle (∆) A closed figure in a plane obtained by joining three non-collinear points is called a triangle. #greenmathskashifhafeez #theorem4 #chapter12 #mathematics #ptbb #linebisector Facebook:   / green-maths-kashif-hafeez-2217308321927927   Instagram: https://instagram.com/greenmaths_kash...
