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.

Step-by-step explanation:
The answer is here. You just multiply the fractions because of L • W
Answer:
100 cars
25 trucks
Step-by-step explanation:
$3c + $5t = $425
c + t = 125 vehicles
($3 * 100) + ($5 * 25) = $425
100 + 25 = 125
Therefore, they washed 100 cars and 25 trucks
Hope this helps!
