a) Two pairs of supplementary angles:
b) A pair of complementary angles:

Please explain this! Thank you!

a) Angles 4,3 and 2,3 are supplementary angles
b) Angles 1,2 are complimentary angles

Explanation:

Supplementary angles are those that form 180 degrees, they beed not be adjacent to each other. Since CB is a straight line, angles 4 plus angle 3 is equal to 180 degrees. Since DE is a straight line, angles 2 plus angle 3 is equal to 180 degrees.

Complimentary angles are those that form 90 degrees, they need not be adjacent to each other. Since CB is a straight line, angle 5 + 1 + 2 is equal to 180 degrees. Since angle 5 is 90 degrees, we can say that angle 1 plus angle 2 is also 90 degrees.
