2. A rotation by angle ACE using point C as the center takes triangle CBA onto triangle CDE

a. Explain why the image of ray C A lines up with ray CE.

b. Explain why the image of A coincides with E.

c. Is triangle CBA congruent to triangle CDE? Explain your reasoning.

the correct answers are 1, 2, 4, and 5! i just got it right!

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.
