Which pairs of triangles can be shown to be congruent using rigid motions? select congruent or not congruent for each pair of triangles.

1--- not congruent

2--not congruent

3---congruent

4---congruent

5---not congruent

6---not congruent

Step-by-step explanation:

This is true because the congruent figures are equal to each other, the not congruent shapes are not congruent because they don't equal each other.(the answers are right but I am quite bad at explaining things)

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
