From the given we see that is isosceles, so .
By the use of alternate interiors angles we get
From that we see that is isosceles.
Surely you can finish it from all the above.
Hi, i;m really stuck on my maths homework.
It's about congruency and stuff, but this is about proving that lines are the same?
Anyhoo, here's the question:
In the diagram, DX = XC, DV = ZC,and the lines AB and DC are parallel. Prove That:
a) AX = BX
b) AC = BD
c) triangles DBZ and CAV are congruent
my roughly drawn diagram to this question is here:
Please help i'm really stuck.
If you need help reading the diagram just ask me what the matter is.
Thankyou sooo much!!
