Congruence Properties
In earlier mathematics courses, you have learned concepts like the commutative or associative properties. These concepts help you solve many types of mathematics problems. There are a few properties relating to congruence that will help you solve geometry problems as well. These are especially useful in two-column proofs, which you will learn later in this lesson!
The Reflexive Property of Congruence
The reflexive property of congruence states that any shape is congruent to itself. This may seem obvious, but in a geometric proof, you need to identify every possibility to help you solve a problem. If two triangles share a line segment, you can prove congruence by the reflexive property.
Answer:
8x2−8xy−6y2
Step-by-step explanation:
if your answer choices contain exponents then of course the number behind the x's are exponents.
Answer:
ln\frac{(x-3)^5}{x^2}[/tex]
Step-by-step explanation:
First use the exponent property alnb=ln(b)^a
Then use the difference property that is lna-lnb= ln(a/b)
X=40 the right angle is 90 degrees and 90-10 = 80, 80 = 2x, so x = 40
