How to determine by plotting if two figures are similar or not

The video tutorial covers plotting coordinate points and graphing images to determine similarity. It explains how to use proportions to prove similarity between triangles and discusses the use of special segments like altitudes, medians, and angle bisectors for proportionality. The tutorial concludes with identifying a reduction in scale factor.

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

• Plotting the points and connecting them

• Calculating the area of the images

• Measuring the angles of the images

• Finding the perimeter of the images

What is the purpose of setting up a proportion between two images?

• To measure the angles of the images

• To determine if the images are similar

• To calculate the volume of the images

• To find the area of the images

Which lines are easiest to use when determining the distance between points?

• Parallel lines

• Curved lines

• Diagonal lines

• Horizontal and vertical lines

What formula is used to find the distance of a diagonal line?

• Perimeter formula

• Distance formula

• Area formula

• Volume formula

Which special segments can be used for proportionality in triangles?

• Chord, tangent, and secant

• Altitude, median, and angle bisector

• Base, height, and hypotenuse

• Radius, diameter, and circumference

What is the scale factor if the new image is a reduction of the original?

• 2

• 1/2

• 3

• 1/3

How can you determine if two triangles are similar?

• By measuring the angles
