The Angle Bisector Theorem states that given triangle and angle bisector AD, where D is on side BC, then . Likewise, the converse is also true. Not sure if this is what you want?
Label the triangle ABC. Draw the bisector of angle A to meet BC at D. Then in triangles ABD and ACD, angle ABD = angle ACD (equiangular triangle) angle BAD = angle CAD (AD is angle bisector) so angle ADB = angle ACD (third angle of triangles). Also AD is common. So, by ASA, triangle ABD is congruent to triangle ACD and therefore AB = AC. By drawing the bisector of angle B, it can be shown that AB = BC. Therefore, AB = BC = AC ie the triangle is equilateral.
It's infinitely small. It can't be defined. Any angle can be divided ad infinitum. The best we can say is that it's close to zero.

1,999 − 396 = 1,603 years. As both numbers are AD, treat as numbers rather than years. Subtract the lowest number from the highest number to get the answer in the number of years between the two dates.There is a difference if one date is BC and the other is AD. Which is another question.
The laws of reflection were formulated by the ancient Greek mathematician and physicist, Euclid. These laws state that the angle of incidence is equal to the angle of reflection, and that the incident ray, the reflected ray, and the normal at the point of incidence all lie in the same plane.

Given: AD perpendicular to BC; angle BAD congruent to CAD Prove: ABC is isosceles Plan: Principle a.s.a Proof: 1. angle BAD congruent to angle CAD (given) 2. Since AD is perpendicular to BC, then the angle BDA is congruent to the angle CDA (all right angles are congruent). 3. AD is congruent to AD (reflexive property) 4. triangle BAD congruent to triangle CAD (principle a.s.a) 5. AB is congruent to AC (corresponding parts of congruent triangles are congruent) 6. triangle ABC is isosceles (it has two congruent sides)
That is not necessarily true.
If AC = 10 units and D is the midpoint of AC then AD = AC/2 = 5 units!
The Angle Bisector Theorem states that given triangle and angle bisector AD, where D is on side BC, then . Likewise, the converse is also true. Not sure if this is what you want?
AC is alternating current and AD is Anno Domini or after Christ.
Because your eye is covered in a moist film which protects the eye a little. It prevents the eye from drying out ad you can see your reflection in it because it is a clear liquid similar ti water.
That is not necessarily true.
