Question

The angles of quadrilateral are 3:4:5:6.Show that quadrilateral is a trapezium with the help of a rough diagram

Answer 1

First angle = 3x
Second angle = 4x
Third angle = 5x
Fourth angle = 6x
We know that sum of all angles of a quadrilateral =360 .
Then, 3x +4x + 5x + 6x = 360
18x = 360
X =360/18
X = 20.
First angle = 60
Second angle = 80
Third angle = 100
Fourth angle =120


In quadrilateral, pair of opposite side are parallel .
In trapezium, there is also a pair of opposite side are parallel.
