Geometry Concepts: Midpoint, Distance, and Undefined Sets

What is the formula used to find the midpoint of a line segment?

• Use the Pythagorean theorem

• Subtract one endpoint from the other and divide by two

• Multiply the x-coordinates and divide by two

• Average the x-coordinates and y-coordinates separately

How do you calculate the distance between two points?

• The square root of the sum of the squares of the differences in x and y coordinates

• Multiply the x-coordinates and subtract the y-coordinates

• Use the midpoint formula

• Add the coordinates and take the square root

Which of the following are considered undefined terms in geometry?

• Midpoints, distances, and segments

• Angles, surfaces, and volumes

• Points, lines, and planes

• Circles, squares, and triangles

Which of the following is not an undefined term in geometry?

• Plane

• Segment

• Line

• Point

What is the result of applying the Pythagorean theorem to a right triangle with sides of 1 and 5 units?

• 26 units

• 6 units

• 25 units

• 5.09 units

What is the perimeter of the given quadrilateral?

• 28.08 units

• 30 units

• 26 units

• 24 units

What is the midpoint of a line segment with endpoints at (-6, 5) and (1, 7)?

• (-2.5, 12)

• (-5/2, 6)

• (-5.5, 12)

• (-2.5, 6)

How is a line segment different from a line?

• A line segment cannot be measured

• A line segment has a definite length

• A line has arrows on both ends, a segment does not

• A line segment has a midpoint, a line does not

What defines a ray in geometry?

• It extends infinitely in both directions

• It has two endpoints

• It extends infinitely in one direction from an endpoint

• It can be measured precisely

What characteristic do parallel lines share?

• They have the same length

• They never intersect

• They intersect at one point

• They form a right angle when they meet
