Exercise 4.3
Question 1
Construct the following quadrilaterals:
(i) Quadrilateral MORE
MO = 6 cm, OR = 4.5 cm, M = 60
0
, O = 105°, R = 105°,
(ii) Quadrilateral PLAN
PL = 4 cm, LA = 6.5 cm,P = 90°, A = 110°, N = 85°
(iii) Parallelogram HEAR
HE = 5 cm, EA = 6 cm, R = 85°
(iv) Rectangle OKAY
OK = 7 cm, KA = 5 cm
Solution:
(i) Steps of construction:
1. Draw a line segment MO = 6 cm.
2. At O, draw an XOR = 105° .
3. From ray OX, cut OM = 6 cm.
4. At R, draw an ORY = 105° .
5. At M, draw OMZ = 60°, the rays RY and MZ
intersect each other at E.
6. MORE is the required quadrilateral.
