Does it work for a square?
Sorry, I meant hexagon.
In general, no, think about a simple equalateral triangle.
how we find an angle of an isosceles tringle if nothing is given.only opposite exterior angle given?
Give me a second, I'll come and help
Good drawing. Let me expand on that.
no not good..i know
I'm assuming that says 35 degrees?
Can you see how I've filled in the other angles? They're all the same, since that horizontal line at the top is parallel to the horizontal line on the bottom.
In answer to your question, that interior angle will indeed be the same as the exterior angle they gave you, in this case.
Here's two general rules:|dw:1327946043669:dw|
I learned them as "vertically opposite angles" and the "Z-rule", I don't know what your teacher might have called them.
Am I confusing you?
yes there is parallel lines
no not at all its 35 degree
Great! All the angles should be 35 degrees then! (except the interior one at the top of the triangle, of course)
No problem! Everything sorted now?
i solved it before but sometimes confussion occur..
It happens. This takes lots of practice.
one more question wait
WXYZ is a quadrilateral in which W = 108 , X = 88 , Y = 57 and WXY = 31.Calculate WZX and XZY.
Listen, I have to go study myself now. Can you copy and paste that into a new question? That way somebody else will be able to help. You should make it clear whether W, X, Y and WXY are - are they lenghts, angles etc? I have to go now though, so make sure you create a new question, so somebody else can answer it.
