Isometry is a transformation the preserves the distance and there is no change in the distances. It includes rotation, reflection and translation . Hence the figures are congruent. So the statement is false
Question 12:
A reflection is a transformation where every point of the line is of equal distance from a particular line called the line of reflection
Hence this statement is true
Question 13:
The angle of rotation is the turning of every angle of a figure about a specific fixed point in a specific degree. Hence the statement is true
<3 +<4= 180 <3+25+52=180 from here <3=180-77=103 using this in first equation: 103+<4=180 <4=180-103=77 as you can see <4=77 which is the the sum of 25+52
