statement reason
1. ∠1 is complementary to ∠2. 1.
2. 2. definition of complementary
3. 3. given
4. 4. definition of bisect
5. m∠2 = m∠3 5.
6. m∠1 + m∠3 = 90° 6.
7. 7.

Given below

Step-by-step explanation:

1. ∠1 is complementary to ∠2. 1.Given

2.  m∠1 + m∠2.=90 degrees 2. Definition of complementary

3.BD bisects ∠ADC. 3. Given

4.  Angle ADB = angle BDC 4. Definition of bisect

5. m∠2 = m∠3   5.  Definition of bisect

6. m∠1 + m∠3 = 90° 6.  substitution

7. Sums add up to 90 degrees. 7. angle 1 is complementary to angle 3.
