Answer: 
Step-by-step explanation:
By the exterior angle theorem, 
Answer:
Right angles are congruent
Step-by-step explanation:
One right angle can be transformed to another using rigid transformations such as translation ,rotation and reflection.This is basically the definition of congruence because the idea is to transform one object to another.
The probability of any particular sequence of N flips of a fair coin is 2^(-N).
Your probability of the given sequence of 3 coin flips is
2^-3 = 1/8
The answer would be false.
Since the figure above is a square, that would mean all sides are equal size. If x=5, that would make segment AD bigger than segment BC.
