Determining multiple missing values using congruent polygons

The video tutorial explains how to determine corresponding parts of congruent polygons without relying on visual cues. It emphasizes using congruence statements to identify congruent angles and sides, and demonstrates solving equations to find variable values. The tutorial guides students through labeling corresponding parts and setting up equations based on congruence to solve for unknowns.

What is the primary piece of information used to determine corresponding parts in congruent polygons?

• The color of the polygons

• The congruence statement

• The size of the polygons

• The visual appearance of the polygons

Why is it important not to rely solely on the visual representation of figures when identifying congruent parts?

• Figures are not important

• Visuals can be misleading

• Visuals are always correct

• Figures are always accurate

Which angles are congruent according to the congruence statement in the video?

• Angle B and Angle T

• Angle C and Angle U

• Angle D and Angle T

• Angle E and Angle R

How can you determine the congruence of side lengths in polygons?

• By measuring them directly

• By using the congruence statement

• By guessing

• By looking at the color

What equation is set up to solve for the variable Y?

• y - 31 = 2y + 11

• 2y - 31 = y + 11

• y + 31 = 2y - 11

• 2y + 31 = y - 11

What is the value of W when solving the equation 4W - 7 = 2W + 3?

• W = 10

• W = 7

• W = 5

• W = 3

What is the final step in solving for Z in the equation 3Z + 10 = Z + 16?

• Divide by 2

• Subtract Z from both sides

• Add 10 to both sides

• Multiply by 3
