NCERT Solutions for Class 8 Maths Chapter 4 Exercise 4.4 – Practical Geometry
1. Construct the following quadrilaterals
i. Quadrilateral DEAR
DE = 4 cm
EA = 5 cm
AR = 4.5 cm
∠E = 60°
∠A = 90°
Solution:
Steps of construction
- Step 1. Draw the side AE = 5 cm
- Step 2. Draw ∠AED = 60°, such that ED = 4 cm
- Step 3. Draw ∠EAR = 90°, such that AR = 4.5 cm
- Step 4. Join R and D
DEAR is the required quadrilateral.
ii. Quadrilateral TRUE
TR = 3.5 cm
RU = 3 cm
UE = 4 cm
∠R = 75°
∠U = 120°
Solution:
Steps of construction
- Step 1. Draw the side RU = 3 cm
- Step 2. Draw ∠URT = 75°, such that TR = 3.5 cm
- Step 3. Draw ∠RUE = 120°, such that UE = 3 cm
- Step 4. Join T and E
TRUE is the required quadrilateral.
