Haven’t done matchs in 16 years but has to be based on the following facts.
DOEC is a quadrilateral, where each angle of the quadrilateral will total 360 degrees.
Since angle ODC and OEC are both 90 degrees the sum of DOE and DCE has to equal 180 degrees.
Because every triangle has to total 180 degrees.
then if we assumed a value for angle DOE or angle DCE we should be able to prove DOC = DEC.
href="https://www.facebook.com/ciaran.kavanagh2" target="_blank">Ciarán Kavanagh
the question is flawed! the angle represented by doc is not equal to that of dec. with c remaining constant in both triangles, the angle at d becomes more acute in dec than it does in doc where it is a right angle….thus the question cannot be answered!
href="https://www.facebook.com/garrett.brien" target="_blank">Garrett O’ Brien
That’s what I thought but when I looked again I saw that what they are talking about is where the two right angle signs are.
href="https://www.facebook.com/colin.brennan.7169" target="_blank">Colin Brennan
Its one of thoses bloody proofs it would take way long to right out… Like these triangles never proved anyway useful in the outside world!
href="https://www.facebook.com/jason.lee.3572" target="_blank">Jason Lee
its to do with trinangles havin 180 degrees total and working out all the angle so that certain angles equal each other usin geometry.

DOC = DEC there is no such angle as O does not join directly to C and D does not join directly to E… its probably wrong but that’s my answer.

What is a guestion? They asked questions in my day. English spelling test fail…
href="https://www.facebook.com/jay.galligan" target="_blank">Jaay Galligan
I would imagine that this question has an error in it, as there is no angle DOC or DEC….

The two angles don’t exit?…been 13 years so I could just be rusty:)
href="https://www.facebook.com/vakaveronica" target="_blank">Ver-Monica Níc An STúdaire
Yes I believe that you are correct. Unless we’re missing something. There is no DOC angle nor DEC angle. There’s a DOE and BOD. Or I’m just blind and rusty at maths too!
href="https://www.facebook.com/gillian.scannell.9" target="_blank">Gillian Scannell
I think DOEC is a cyclic quadrilateral and that both angles are equal because they lie on the arc DC?? Not sure :-/
href="https://www.facebook.com/peter.machale" target="_blank">Peter MacHale
O is the orthocentre of the triangle ABC, draw a line from C perpendicular to AB and it will go through O. This will show you the angle DOC. Then draw a line from D to E to show the angle DEC.
href="https://www.facebook.com/lowcarbken" target="_blank">Ken Armstrong
Yes, DOC = DEC Both are right angles – Can I have my 500 points now.
href="https://www.facebook.com/chris.primo.5" target="_blank">Chris Primo ·Â The two angles (<DOC and <DEC) do not exist.

The angles do exist – they just ain’t drawn in…
