Final Jeopardy

When enlarging or reducing a figure, what two things stay the same?

Angles and Shape

When enlarging and reducing a figure, what three things change?

Side lengths, area and perimeter

Yes or No:

Are the following figures similar? EXPLAIN!!!

NO! The corresponding angles are not the same.

True or False

Similar and congruent mean the same thing.

False

If the dimensions of a picture are 4 x 8, what would the new dimensions be if you copied it using 250%?

10 x 20

4 x 2.5 = 10

Which side does AB correspond with in Figure 2?

Side EF

What angle corresponds with angle C?

Angle F

Which side corresponds with side DC?

Side TS

Name one pair of corresponding sides.

ABCDE ~ VWXYZ

Any two letters in order.

ABCDE ~ VWXYZ

Name two pairs of corresponding sides and one pair of corresponding angles.

TUVWX ~ OPQRS

Any two letters in order and any corresponding angles

Which of the following rules is similar to Mug (x, y)

(3x, 2y)

(1.5x, 1.5y)

(x, 3y)

(4x, y)

b. (1.5x, 1.5y)

Why is Mug (x, y) similar to Zug (2x, 2y)? Explain!

x and y are multiplied by the same scale factor.

Explain what would happen to a figure if you transformed it using the given rule:

(2x, 4y)

.

The figure would be 2 times wider and 4 times taller.

Explain what would happen to a figure if you transformed it using the given rule:

(x + 2, y + 4)

The figure would move to the right

two spaces and up four spaces.

Write the rule for Blug compared to Mug (x, y) if Blug moves left 3 spaces and down 5 spaces.

(x – 3, y – 5)

If the dimensions of rectangle A are 3 x 5, what would be the dimensions of rectangle B if the scale factor from A to B is 4?

Rectangle B = 12 x 20

B = 2.5

What is the scale factor from Rectangle B to Rectangle A?

B – A = 1/3

How many degrees are in a triangle?

What is the measure of the missing angle?

180 – 31 – 39 = 110

What are the measures of the angles in an equilateral triangle?

If the sum of two angles in a triangle is 142 degrees, what is the measure of the third angle?

Name three types of triangles

Right, scalene, equilateral, isosceles
