1) Measures of angles of ABCD are in the ratio 4:5:7:8. Show that ABCD is a trapezium

Solution Let measures of 2A, 2B, 2C and 2D be (4x)”. (5x)”.(7x) and (8x) respectively

, “.

4x + 5x + 7x + 8x = 360°

* = 360

D

(Br) (7x)

(5x)

А

# !!

Now

A=4x = 4x

B = 5x = 5 x

LC = 7x = 6

2D = 8x = 7

2B + 4 =

side CD || side BA

But. 28+ A- O 180

side BC and side AD are not parallel

DABCD is
