Answer:

You use the Pythagorean Theorem or a²+b²=c²

a and b are the two shorter sides, c is the hypotenuse, the longest side.

Step-by-step explanation:

I will do them for you:

     12²+16²=20²

   144+256=400

           400=400

Triangle XYZ is a Right Triangle :)

    15²+20²=25²

  225+400=625

           625=625

Triangle PQR is a Right Triangle :)

PLEASEE HELPP!!!
Mandarinka [93]

Answer:

AB/DE=BC/EF=AC/DF

Step-by-step explanation:

Corresponding segments are designated by letters in corresponding positions in the triangle names. For example, of one segment is designated using the 1st and 2nd letters of one triangle name (such as AB), then the corresponding segment is designated using the 1st and 2nd letters of the other triangle name (such as DE).

Corresponding segments are proportional in length. Corresponding angles are congruent.
