d. SAS congruence postulate
<h3>Triangle Congruence Postulates or Theorems</h3>
- Two triangles having two pairs of congruent angles and a pair of included sides are congruent by the SAS congruence postulate.
- Two triangles having three pairs of congruent sides are congruent by the SSS congruence postulate.
- Two triangles having two pairs of congruent sides and a pair of included angles are congruent by the SAS congruence postulate.
- Two triangles having two pairs of congruent angles and a non-included side are congruent by the SAS congruence postulate.
Therefore, the congruence theorems or postulates that proves the following set of triangles are congruent are:
a. SAS congruence postulate
b. SSS congruence postulate
c. SAS congruence postulate
d. SAS congruence postulate

Answer:
Step-by-step explanation:
y=2x1-
So this is a very simple question.
First, analyze the problem
It says y=2x-1
The answer is +1 or 1 I believe
Someone pls correct me If I'm wrong.
What is the product of 2.31 and 0.21?
Solution:
We need to find 2.31*0.21
Let us first find 231*21, then we would consider decimals
231*1=231
231*2=462
So, 231*21=231+4620=4851
So, we get 231*21=4851
But, we need to find, 2.31*0.21
There are two numbers after decimal in 2.31 (3 and 1). and, there are two numbers after decimal in 0.21(2 and 1)
So, In result of, 2.31*0.21 there must be four digits after decimal.
As, 231*21=4851
So, 2.31*0.21=0.4851 (four digits after decimal)
Answer:0.4851
let's firstly convert the mixed fractions to improper fractions and then multiply.
