Step-by-step explanation:
Ok, imagine I have a finger pointed up, and you have your's as well. They are not congruent / parallell to each other because they are not in the same plane.
Plane: A plane is kind of the space around you, so take a paper and draw a line, the space around the line is called a plane. To make two lines parallell, they have to be straight and be in the same plane
Congruence/congruent= Equal(led) to
Postulates means that you know it without proof, for example, a right angle is 90 degrees.
There are different congruence postulates. It can be used for triangles or for other shapes.
I hope this answers your question, I am not to sure on what you said !
Answer:
a = 12 and b = 18
Step-by-step explanation:
Given that,
8,a,b,27 are in geometric sequence.
For a GP, the nth term is given by :

Put n = 4

Put n = 2,

Put n = 3

So, the values of a and b is 12 and 18 respectively.
Answer:3 is nonlinear ,1 is function ,domain is the input and the range is the output, mx is the slope and the b is the y intercept
Step-by-step explanation:
Answer:
50% is the answer.
Step-by-step explanation:
All three persons have different blood groups.
Mary has O blood type.
Her husband has B blood type.
Her father in law has A blood type.
As everyone has different blood groups and the child's group depends on parents blood groups so we have 2 options left.
Hence, the probability that the child will have type O blood is =
=50%
