Question

ABCD is a square. ABO is an equilateral triangle
inside the square. Find angle DOC. "plzz help me in this questionplzzz​

Answer 1

90degrees

vertical opposite angles are equal here, if we draw two diagonals we get 4 angles

AOB,BOC,COD and DOC

as vertically opposite angles are equal we get DOC and AOB are equal and DOA and COB are equal

so here 4 equal angles then if angle measure x degrees

4x=360 degrees so 1 angle is 90 degrees

then, DOC angle measures 90 degrees
