Показать описание
• 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.
• Congruent Triangle:
Two triangles are said to be congruent, If there exists a corredpondence between them such that all the corresponding sides and angles are congruent.
