Question

Construct a quadrilateral ABCD in which AB=5cm,BC=5cm, angle A = 60°, angleB =120°,angleC = 90° Measure angle D​

Answer 1

Step-by-step explanation:

Step 1- A line segment of 5 cm is taken.

Step 2-Draw an angle of 60 degree at point A.

Step 3-Draw an angle of 120 degree at point B.

Step 4-Now take an arc of 5 cm and cut at point C.

Step 5-And draw 90 degree at point C .

Step 6- Join AB,BC,CD and DA.

Measure of D=?

Angle A + Angle B + Angle C + Angle D= 360 degree

so, 60 + 120 + 90 + angle D= 360 degree

270 +angle D=360 degree

Angle D=360-270=90 degree
