Triangle Enlargement Concepts

The video tutorial explains the process of enlarging a shape using a scale factor. It covers the necessary components for enlargement: the object, the point of enlargement, and the scale factor. The tutorial demonstrates enlarging a right-angle triangle from a specific point with a scale factor of two, showing how each point of the triangle is repositioned. The result is a triangle that is twice the size and twice as far from the point of enlargement, maintaining its shape and proportions.

What are the three essential components needed to solve an enlargement question?

• Object, angle, distance

• Point of enlargement, angle, scale factor

• Object, point of enlargement, scale factor

• Object, scale factor, angle

In the given example, what shape is being enlarged?

• Right angle triangle

• Circle

• Rectangle

• Square

What is the significance of the point of enlargement?

• It is the reference point from which the shape is enlarged

• It affects the shape's material

• It changes the shape's orientation

• It determines the color of the shape

What does a scale factor of 2 imply in the context of enlargement?

• The shape's perimeter is halved

• The shape's area is doubled

• All points are twice as far from the point of enlargement

• The shape's color changes

How far across and down is point A moved when enlarged with a scale factor of 2?

• 8 across, 2 down

• 4 across, 1 down

• 6 across, 3 down

• 10 across, 5 down

What is the new position of point B after enlargement?

• 3 across, 3 down

• 6 across, 6 down

• 9 across, 9 down

• 12 across, 12 down

After enlarging point C, what are the new coordinates?

• 4 across, 3 down

• 16 across, 12 down

• 8 across, 6 down

• 12 across, 9 down

What remains unchanged about the triangle after enlargement?

• Its position

• Its color

• Its right angle property

• Its size

How does the base of the triangle change after enlargement?

• It remains the same

• It is halved

• It is doubled

• It is tripled

What happens to the height of the triangle after enlargement?

• It remains the same

• It is halved

• It is doubled

• It is tripled
