ABCD – square whose diagonals intersect at point O. Line segment DP – bisector of triangle COD. Calculate the degree scintillation of the CDP angle.

When dividing a square with diagonals, 4 equal right-angled isosceles triangles are obtained.

<COD = 90 °;

<OCD = <ODC;

<COD + <OCD + <ODC = 180 °;

90 ° + <ODC * 2 = 180 °;

<ODC = 45 °.

<CDP = <ODC / 2 = 45 ° / 2 = 22.5 °.

Answer: 22.5 °.
