You have learnt how to draw triangles in Class VII. We require three measurements (of sides and angles) to draw a unique triangle. Since three measurements were enough to draw a triangle, a natural question arises whether four measurements would be sufficient to draw a unique four sided closed figure, namely, a quadrilateral.
Constructing a Quadrilateral
How to construct/draw 60 degrees angle with compasses only
How to construct/draw 90 degrees angle with compasses only
How to construct/draw 105 degrees angle with compasses only
How to construct/draw 85 degrees angle with compasses only
How to construct/draw 110 degrees angle with compasses only
How to construct/draw 60 degrees angle without protractor
How to construct/draw 90 degrees angle without protractor
How to construct/draw 105 degrees angle without protractor
How to construct/draw 85 degrees angle without protractor
How to construct/draw 110 degrees angle without protractor
When three sides and two included angles are given Under this type, when you draw a rough sketch, note carefully the “included” angles in particular.
Example 4: Construct a quadrilateral ABCD, where AB = 4 cm, BC = 5 cm, CD = 6.5 cm and angle B = 105 degrees and angle C = 80 degrees.
EXERCISE 4.4
1. Construct the following quadrilaterals.
(i) Quadrilateral DEAR (ii) Quadrilateral TRUE
DE = 4 cm TR = 3.5 cm
EA = 5 cm RU = 3 cm
AR = 4.5 cm UE = 4 cm
angle E = 60 degrees angle R = 75 degrees
angle A = 90 degrees angle U = 120 degrees
