 an angle of 1 minute is an angle of 1 second. 



Table 

 60 seconds - 1 minute. 

 60 minutes = 1 degree. 

 90 degrees = 1 right angle L. 



Parallel lines are straight lines at any distance from each other 

 which remain at that distance, however far projected in either di- 

 rection (Fig. A). 



A quadrilateral is any figure bounded by four Etraight lines 

 (Figs. B to F inclusive). 



A parallelogram is a quadrilateral whose, c: posite sides are 

 parallel (Figs. C, E and F). 



A trapezoid is a quadrilateral, only two of whose opposite sides 

 are parallel (as per Fig. D, taking either line as its right h&nd 

 boundary).
