construct a quadrilateral ABCD in which AB=6cm AD=5cm angle A=60 degree angle B =100 angle D=110 degree
Answers
Given: AB = 6 cm, BC = 5cm, angle A = 55 degree, angle B = 110 degree and angle D = 90 degree.
Steps;
Angle sum property of a quadrilateral:
∠A + ∠B + ∠C + ∠D = 360 degree
55 + 110 + ∠C + 90 = 360 degree
∠C = 105 degree
1. Draw AB = 6 cm.
2. Take A as a centre construct an angle of 55 degrees and then from B make 110 degrees.
3. Take the measurement of BC = 5cm on the compass and cut the angle 110 line. Mark the point as C.
4. Now take C as a centre and construct 105 degrees.
5. The point where angle C and D will meet will be D.
