2nd Class Mathematics Geometrical Figures Rectangle

  Rectangle

 

 

In a rectangle:

Opposite sides are equal;

Opposite sides are parallel; All angles are equal  

See the figure given below:

 

 

Here, AB = CD and AC = BD Also, angle A = angle B = angle C = angle = D  

 

 

 

• Line has negligible width.
• Triangle has three sides and three angles.
• Square has four equal sides.
• Opposite sides of a rectangle are equal and parallel.
• Square and rectangle are quadrilaterals.  

 

 

 

• Geometrical shapes are two, three of more dimensional.
• Geometry is the mathematical study of shapes, figures and position. It is useful in architecture and carpentry.
