Front

What is the formula for the area of a sector in a circle?

Back

Area = (θ/360) * π * r², where θ is the angle in degrees and r is the radius.

Front

What is the relationship between the sides of similar triangles?

Back

The ratios of the lengths of corresponding sides are equal.

Front

How do you calculate the perimeter of a triangle?

Back

Perimeter = side1 + side2 + side3.

Front

What is the probability of flipping heads three times in a row with a fair coin?

Back

1/8, since (1/2) * (1/2) * (1/2) = 1/8.

Front

What is the definition of a circumcenter in a triangle?

Back

The circumcenter is the point where the perpendicular bisectors of the sides of the triangle intersect.

Front

How do you find the length of a diagonal in a rectangle?

Back

Use the Pythagorean theorem: d = √(length² + width²).

Front

What is the formula for the area of a rectangle?

Back

Area = length * width.

Front

What is the definition of similar triangles?

Back

Triangles that have the same shape but may differ in size; their corresponding angles are equal.

Front

How do you calculate the area of a triangle?

Back

Area = (1/2) * base * height.

Front

What is the formula for the circumference of a circle?

Back

Circumference = 2 * π * r, where r is the radius.
