Acute Angle: Less than 90 degrees
Right Angle: 90 degrees
Obtuse Angle: More than 90 degrees
Straight Angle: 180 degrees
I think I have the diagram right.
Let ADB = x, and then BDC = x+32.
x+x+32 = 90
2x = 58
x = 29 = ADB
so BDC = 61
Explanation:
1. BF bisects ∠CBA. Given
2. ∠CBF ≅ ∠ABF. Definition of angle bisector
3. BF ≅ BF. Reflexive property
4. ∠CFB ≅ ∠AFB. Given
5. ΔCBF ≅ ∆ABF. ASA congruence postulate
6. CF ≅ FA. Corresponding parts of congruent triangles are congruent (CPCTC)
