Question

Triangle 1 is transformed as shown in the diagram, resulting in triangle 3. Describe the transformations.

A) dilation, then reflection
B) rotation, then translation
C) reflection, then translation
D) translation, then reflection

Answer 1

Triangle 1 - 2 shows a translation. A translation is when the triangle doesn't change shape, rotation, or size. It just slides. The 2- 3 shows a mirror image, which would be a reflection. Therefore, your answer is D.

Answer 2

D) translation, then reflection

Explanation:

First the triangle 1 is translated in the right side to make triangle 2. Then the 2 triangle is reflected over to get triangle 3.

So, the correct answer is - translation, then reflection

In reflection transformation, the figure is reflected or flipped on a line called the axis of reflection or line of reflection. And translation means moving or shifting of a figure.
