Geometry Honors TNReady Review Practice 1

Front

What is the midpoint formula in a coordinate plane?

Back

The midpoint formula is: M = ((x1 + x2)/2, (y1 + y2)/2). It calculates the point that is exactly halfway between two given points (x1, y1) and (x2, y2).

Front

Calculate the midpoint between the points (2,6) and (4,8).

Back

The midpoint is (3,7).

Front

What is the formula for the volume of a cylinder?

Back

The volume V of a cylinder is given by the formula: V = πr²h, where r is the radius and h is the height.

Front

If a cylinder has a radius of 15 inches and a height of 3.5 feet, what is its volume in cubic feet?

Back

The volume is approximately 17.2 cubic feet.

Front

What is the definition of a geometric shape?

Back

A geometric shape is a set of points that form a specific figure in a plane or space, such as circles, triangles, and polygons.

Front

What is the difference between a radius and a diameter?

Back

The radius is the distance from the center of a circle to any point on its circumference, while the diameter is twice the radius, measuring the distance across the circle through its center.

Front

Define a polygon. Give an example.

Back

A polygon is a closed figure formed by a finite number of straight line segments. An example is a triangle.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

Front

How do you find the area of a triangle?

Back

The area A of a triangle can be calculated using the formula: A = 1/2 * base * height.

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.
