Using the transitive property of congruence if cd=ef and ef=gh then

The correct option is C. CD = GH

Step-by-step explanation:

We are given in the question that :

CD = EF and EF = GH

we need to use the transitive property of congruence

Transitive Property of Congruence : It states that two objects that are congruent to a third object are also congruent to each other.

Now, CD is congruent to EF and GH is also congruent to EF

So, By using the above transitive property of congruence :

CD must also be congruent to GH

Hence, The complete statement will be : If CD = EF and EF = GH then CD = GH

Therefore, The correct option is C. CD = GH

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
