4. ΔADB ≅ ΔADC by the HL theorem, so all corresponding parts of the triangles are congruent.

Segment AD bisects both angle BAC and segment BC. So, point D lies on the perpendicular bisector of BC.

Yes, there is enough information to answer the questions.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

these are pretty self explanatory if you know what supp right and com angles are
