3Two distinct points in the plane determine a _________________ line.
4.In the following figure AB || CD. Find the measure of ∠BOC. 12. If P, Q, and R are collinear points, then name all the line segments determined by them. 13. Find the complement of 36° 14. Find the measure of an angle that is 26° more than its complement.
5 If a ray CD stands on a line AB, then prove that ∠ACD + ∠BCD=180°

Answer 1

Answer:- zero triangles..

1) we can't draw a triangle with these angles in a triangle.

The sum of all the angles should be 180 degree but the given angles are 45 ,64, 72 if we add these we get 45 + 64 + 72 = 181.

so we can't draw triangle.
