RBSE Class 8 Maths Solutions Chapter 4 Practical Geometry Ex 4.4

Question 1.
Construct the following quadrilaterals.
(i) Quadrilateral DEAR
DE =4 cm
EA =5 cm
AR = 4.5 cm
∠E = 60°
∠A= 90°
Answer:
Quadrilateral DEAR
Draw a rough sketch of the given quadrilateral as given below:

• Step 1: Draw a line segment DE of 4 cm and mark an angle of 60° at point E. Cut a line segment EA of 5 cm from its ray as vertex A.
• Step 2: Draw an angle of 90° at point A. Cut a line segment AR of 4.5 cm.
• Step 3: Join D to R.

Thus, we get the required quadrilateral DEAR.

(ii) Quadrilateral TRUE
TR = 3.5 cm
RU = 3 cm
UE = 4 cm
∠R = 75°
∠U = 120°
Answer:
Quadrilateral TRUE
Draw a rough sketch of the given quadrilateral as given below:

• Step 1: Draw a line segment RU of 3 cm and at point R make an angle of 75°. Cut a line segment RT of 3.5 cm.
• Step 2: Construct an angle of 120° at point U. Now, from U cut a line segment UE of 4 cm.
• Step 3: Join RT to ET.

Thus, we get the required quadrilateral TRUE.
