Answer:

Explanation:

Given: AC is a bisector of ∠BCD

DC ⊥ AD

BC ⊥ AB

To prove : BC ≅ Dc

Statements Reasons

1). AC bisects ∠BCD 1). Given

2)∠ACB ≅ ∠ACD 2). AC is a bisector of ∠BCD

3). DC ⊥ AD 3). Given

4). m∠ADC = 90° 4). DC is perpendicular to AD

5). BC ⊥ AB 5). Given

6). m∠ABC = 90° 6). BC is perpendicular to AB

7). ∠ABC ≅ ∠ADC 7). Right angles are congruent

8). AC ≅ AC 8). Reflexive property

9). ΔABC ≅ ΔADC 9). AL property of congruence

10). BC ≅ DC 10). CPCTC
