1. Construct the following quadrilaterals.(1) Quadrilateral DEARDE = 4 cmEA=5 cmAR=4.5 cmZE = 60°ZA=90° |
|
Answer» (1)A rough sketch of this quadrilateral can be drawn as follows. (2) Draw a line segment DE of 4 cm and an angle of 60º at point E. As vertex A is 5 cm away from vertex E, cut a line segment EA of 5 cm from this ray. (3) Again draw an angle of 90º at point A. As vertex R is 4.5 cm away from vertex A, cut a line segment RA of 4.5 cm from this ray. (4) Join D to R. DEAR is the required quadrilateral |
