Triangle ABC is a right triangle. Point D is the midpoint of side AB and point E is the midpoint of side AC. The measure of angle ADE is 68°.

Triangle ABC with segment DE. Angle ADE measures 68 degrees.

The flow chart with missing statements and reasons proves that the measure of angle ECB is 22°.

Statement: Measure of angle ADE is 68 degrees , Reason: Given, and Statement: Measure of angle DAE is 90 degrees, Reason: Definition of right angle, leading to Statement 1 and Reason 2, which further leads to Statement: Measure of angle ECB is 22 degrees, Reason: Substitution Property
