Answer with explanation:

Vertices of Triangle are (7, 6), (6, 3), and (8, 3) .

When the triangle is transformed that is rotation has taken place and the  coordinates of vertices of Image are (6, −7), (3, −6), and (3, −8).

When you will compare Pre image and Image

1.⇒ Rotation in clockwise direction has taken place to get the Image.

2.⇒Pre Image is in First Quadrant, and Image is in fourth Quadrant

Among the four transformation , Reflection, Rotation, Translation and Dilation , in first three that is, Reflection, Rotation,and Translation Preimage and Image are Congruent , while in Dilation the two, Preimage and Image are Similar.

So , Yes the two triangles are Congruent.

⇒Option A: Yes, the transformation is a 90° clockwise rotation.

In the image, point A is the center of the circle. Which two line segments must be equal in length?
alex41 [277]
The answer is C (EF and HI)

This is because both lines pass through the centre A, meaning both are diameters. Hence, they are equal in length.
