Which of the following is a validation of congruency between two polygons?
a) if by applying only rotation you can make them coincide
b) if by applying only translation you can make them coincide
c) if by applying rigid motions you can make them coincide
d) if by applying dilation you can make them equal

The correct answer is: C) if by applying rigid motions you can make them coincide

Step-by-step explanation:

Two polygons are said to be congruent or identical in form, if they have exactly the same size and shape or if their corresponding angles and sides are also equal. When a rigid motion like - reflection, rotation and translation is applied on the polygons and they maintain the same length and shape then, they are congruent.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
