The letters of each proposed conguency statement need to be in corresponding positions of the original congruency statement
For example, consider the first answer selection. The letters on the left (CBA) are the 3rd, 2nd, and 1st letters of the original congruency statement. The letters on the right (MNL) are the 2nd, 3rd, and 1st letters of the original. The order 321 is not the same as the order 231, so the first choice is <em>incorrect</em>.
Appropriate choices are
∆BAC ≅ ∆MLN . . . . 3rd choice
∆ACB ≅ ∆LNM . . . . 4th choice
Looks to me like a trapezoid
Edit: Isosceles trapezoid
Answer:
What is the question?
Step-by-step explanation:
are length is radius * angle is radians
36 * pi/180=pi/5
arc length = 10 * pi/5 =2* pi
the arc length is approximately 6.28
