Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width)

Front

What is the formula for the area of a rectangle?

Back

Area = length × width

Front

If a rectangle has a perimeter of 40 cm, what is the relationship between its length and width?

Back

The sum of the length and width must equal 20 cm.

Front

How do you calculate the total number of items in multiple sets?

Back

Multiply the number of sets by the number of items in each set.

Front

What is the total number of markers in 26 sets if each set contains 100 markers?

Back

2,600 markers (26 × 100 = 2,600)

Front

What is the sum of angles in a triangle?

Back

The sum of angles in a triangle is always 180°.

Front

If angle SRT measures 35° and angle TRV measures 65°, how do you find angle SRV?

Back

Angle SRV = 180° - (angle SRT + angle TRV) = 180° - (35° + 65°) = 110°.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they never intersect and are always the same distance apart.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if they intersect at a right angle (90°).

Front

What is a frequency table?

Back

A frequency table is a way to organize data to show how often each value occurs.
