Question

how to construct these quadrilareral

Answer 1

using the 4 line it must have 360 degere which means the 2 equatorial triangles one facing up wards onther down

Answer 2

Step 1: Draw a line segment of 4.5 cm and mark it as OP.
Step 2: From point O, draw an arc of 3cm (upside).
Step 3: Now from point M, draw an arc of 2.5cm cutting the arc drawn before.
Step 4: Mark it as point P, where we have drawn the arcs cuting each other.
Step 5: Now join the point P with point O and point M.
Step 6: From point M, draw an arc of 4cm (down) and mark it as point N.
Step 7: Now join point O and point M with point N.

Therefore, it is a quardrilateral MNOP.
