Isosceles = 2 angles same length (36 & 36)
As all the angles are written in, there is a set length of each side, so it is isosceles

But how should I write the answer thats what confuses me.
Just show how you got each angle and then state what I said above

Maths watch is terrible for this sort of question as you need to exactly match the words they want.

Start with angle BDA = 72 [angles opposite the equal sides in an isosceles triangle are equal]

Then carry on - then submit and see what it says. I've helped a lot of people with these questions in the past and they are a nightmare.

How to I show that
I would say, angle BCD is isosceles because each angle adds up to 180. Then just show the working out which is: 36+36=72 then 108+72=180

It's been ages since I've used Mathswatch but does it give you the answer if you failed the question?
