The type of relationship that angle a and angle b have is that they are complementary.
<h3>What are Complementary Angles?</h3>
A right angle equals the measure of 90 degrees. If two angles equals a right angle, then their sum equals 90 degrees. Complementary angles have a sum of 90 degrees, therefore, if two angles form a right angle, then they are a pair of complementary angles.
In the image given, angle a and angle b form a right angle. Thus, the sum of angle a and angle b equals 90 degrees. This means they are complementary angles.
Therefore, the type of relationship that angle a and angle b have is that they are complementary.
