Determining the scale factor of the enlargement of a triangle

The video tutorial explains how to determine if two triangles are similar by using proportions. It discusses the concept of enlargement and how to calculate the scale factor by comparing the lengths of corresponding sides. The tutorial emphasizes the importance of understanding proportions and provides a step-by-step guide to finding the scale factor, ensuring that students can identify whether a transformation is an enlargement or reduction.

What is the purpose of separating the smaller triangle from the larger triangle in the problem?

• To make it easier to compare their sizes

• To determine the color of the triangles

• To change the shape of the triangles

• To find the area of the triangles

What is the first step in determining if two triangles are similar?

• Finding the area of each triangle

• Measuring the angles of each triangle

• Calculating the perimeter of each triangle

• Creating a proportion between corresponding sides

What does it mean if the transformation from triangle A to triangle B is an enlargement?

• Triangle A is the same size as triangle B

• Triangle A is smaller than triangle B

• Triangle A is larger than triangle B

• Triangle A is a different shape than triangle B

How do you find the scale factor (K) between two similar triangles?

• By comparing the lengths of corresponding sides

• By measuring the angles of the triangles

• By calculating the area of each triangle

• By finding the perimeter of each triangle

What is the scale factor if a side of triangle A is 4 and the corresponding side of triangle B is 8?

• 4

• 2

• 1

• 0.5
