Question

identify the image of triangle XYZ for a composition of 50 degrees rotation and a 40 degrees rotation, both about point y

Answer 1

Answer:

The correct option is A.

Step-by-step explanation:

If the direct of rotation is not mentioned, then it is consider as counterclockwise rotation.

It is given that triangle XYZ rotated 50 degrees and a 40 degrees, both about point Y.

It means the figure triangle XYZ rotated 90 degrees counterclockwise  about the point Y.

In option A, triangle XYZ rotated 90 degrees counterclockwise  about the point Y.

In option B, triangle XYZ rotated 180 degrees counterclockwise about the point Y.

In option C, triangle XYZ rotated 270 degrees counterclockwise  about the point Y.

In option D, triangle XYZ rotated 360 degrees counterclockwise  about the point Y.

Therefore the correct option is A.

Answer 2

Answer:

a

Step-by-step explanation:

Given:

triangle XYZ  is rotated by a composition of 50°+40°=90° both about point y

Now when a geometrical figure is rotated by any degree then its shape or size does not change and remain same.

As the triangle is rotated clockwise by 90  degrees about point y then diagram attached is formed .

option a is correct.
