Question

if the angles of a quadrilateral taken in order are in the ratio 1: 2 : 3 :4 prove that it is a trapezium.
ch- mid point theorem

Answer 1

let the coefficient of the following ratios be x.
we know that sum of angles of quadrilateral equals 360°.

So,
1x+2x+3x+4x = 360.
10x = 360°.
x = 36°.

First angle = 36°.
Second angle = 72°.
Third angle = 108°.
Fourth angle = 144°.
