Ex 4.4, 1 (i) Construct the following quadrilaterals. Quadrilateral DEAR DE = 4 cm EA = 5 cm AR = 4.5 cm ∠E = 60° ∠A = 90°
Let’s draw a rough sketch
Let’s construct it
Steps of construction
1. Draw side EA of length 5 cm
2. We draw 60° from point E
Check Construction 11.1 NCERT to see how to draw 60°
3. We draw 90° from point A
Check Ex 11.1, 1 of Chapter 11 Class 9 NCERT to see how to draw 90°
4. Taking 4 cm as radius, and E as center.
Draw an arc. Mark the point where arc and line intersect as D
Taking 4.5 cm as radius, and A as center.
Draw an arc. Mark the point where arc and line intersect as R
6. Join DR
Label the sides
∴ DEAR is the required quadrilateral
