Based on one of the Triangle Congruence Postulates, the two triangles are shown are congruent
tankabanditka [31]

Answer:

true

Step-by-step explanation:

all the sides match up. One side (the base) is shared which means they are the same length. The triangle at the top has a single hash on a side and so does the bottom one. This means they are the same length. The same thing occurs with the last remaining sides, they are congruent because they both have two hash lines. Since all three sides of both triangle add up, the triangles ARE CONGRUENT.

How can u use number patterns to find the least common multiple of 120 and 360
Natasha2012 [34]
A number pattern would be something that just gets repeated over and over 
so for this example 120+120+120=360

so the least common multiple is 120 because adding 120, three times will get you to 360
