Exploring Sequence of Transformations

What is the goal of the lesson?

• To identify different types of triangles

• To describe a sequence of transformations

• To measure angles in a triangle

• To calculate the area of a triangle

Which image is the original triangle?

• The one with no marks

• The one with one mark

• The one with two marks

• The one with three marks

What is the ordered pair for point A in the original triangle?

• (2, 4)

• (-4, 2)

• (6, 4)

• (-4, -2)

What transformation is applied first to the original triangle?

• 90-degree clockwise rotation

• 90-degree counterclockwise rotation

• Translation

• Reflection over the y-axis

What is the ordered pair for point B after the first transformation?

• (4, 6)

• (-4, 6)

• (-4, -6)

• (6, 4)

What is the second transformation applied to the triangle?

• Translation

• 90-degree clockwise rotation

• Reflection over the y-axis

• Reflection over the x-axis

What is the first transformation in the new example?

• Reflection over the x-axis

• Translation

• 90-degree counterclockwise rotation

• 180-degree rotation

How many units right and up is the translation in the new example?

• 4 right and 4 up

• 2 right and 4 up

• 4 right and 2 up

• 2 right and 2 up

What is the second transformation in the new example?

• Translation

• Reflection over the y-axis

• 180-degree rotation

• 90-degree counterclockwise rotation

What is the ordered pair for point C after the second transformation in the new example?

• (6, 8)

• (4, 6)

• (-4, -6)

• (-6, -8)
