Math 3 EOC Prep 1

Front

What is an increasing interval in a function?

Back

An increasing interval is a range of x-values where the function's output (y-values) increases as x increases.

Front

What is a perpendicular bisector?

Back

A perpendicular bisector is a line that divides a segment into two equal parts at a 90-degree angle.

Front

What is the centroid of a triangle?

Back

The centroid is the point where the three medians of a triangle intersect, and it is also the triangle's center of mass.

Front

How do you find the arc length of a circle?

Back

Arc length can be found using the formula: \( L = r \theta \), where \( r \) is the radius and \( \theta \) is the angle in radians.

Front

How do you convert radians to degrees?

Back

To convert radians to degrees, use the formula: \( degrees = radians \times \frac{180}{\pi} \).

Front

What is the formula for the area of a circle?

Back

The area of a circle is given by the formula: \( A = \pi r^2 \), where \( r \) is the radius.

Front

What is the difference between a median and a midsegment in a triangle?

Back

A median connects a vertex to the midpoint of the opposite side, while a midsegment connects the midpoints of two sides.

Front

What is the circumcenter of a triangle?

Back

The circumcenter is the point where the perpendicular bisectors of the sides of a triangle intersect, and it is the center of the circumscribed circle.

Front

What is the orthocenter of a triangle?

Back

The orthocenter is the point where the altitudes of a triangle intersect.

Front

What is the formula for the circumference of a circle?

Back

The circumference of a circle is given by the formula: \( C = 2\pi r \), where \( r \) is the radius.
