Question

construct a quadrilateral PQRS in which PR=10cm and PR=2 PQ.also triangle PRS is an equilateral triangle and angle Q=90 degree.

Answer 1

Step-by-step explanation:

First make PS = 10 cm and make a semicircle and then make a arc from both end of semi circle of 60⁰.

Then cut the arc by line passing through both arc and then the line meet at end on R. this form equilateral triangle of 60⁰ .

the make 90⁰on angle Q angle by making arc from both end of line PR.

Then join P and Q by line.

Your quadrilateral is ready.
