I assume that points BC is a straight line and that D is the point where the line DE intersects BC. If this is so, and CDE is 55 degress, then BDE is 125 degrees.
Line AB is perpendicular to BC. you can say this like; Line AB is at a right angle to BC
it means the dates of the past like bc is the same as bce which id the decrease of dates like 524bce to 520bce is 2 years but ad is the opposite

It Separates BC (Line on top) into two congruent line segments.
B.C. years are like negative numbers on a numberline counting down then counting up again once it hits A.D. (A.D. years are positive numbers on a number line)
It is thought that the first use of numbers was about 30,000 BC. The earliest known base 10 system dates to about 3100 BC in Egypt.
