Assignment 1
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
