Geometry Essentials

Charlotte and Mia are working on a project where they need to form an angle using two smaller angles. If the sum of these two smaller angles is 90 degrees, what type of angle have they formed?

• Acute angle

• Right angle

• Obtuse angle

• Complementary angles

Harper and Jackson are standing on two different roads that are parallel to each other. Which of the following is a characteristic of the roads on which Harper and Jackson are standing?

• They intersect at a 90-degree angle

• They never intersect

• They intersect at a point

• They always intersect at two points

Aria, Oliver, and Arjun are playing a game of darts. The dartboard is circular, and they notice that the distance from the center of the dartboard to any point on the edge is always the same. What do they call this distance?

• Radius

• Diameter

• Chord

• Secant

During a geometry class, Abigail, Hannah, and Henry were discussing different types of angles. They came across an angle that is more than 90 degrees but less than 180 degrees. Can you help them identify the type of this angle?

• Acute angle

• Right angle

• Obtuse angle

• Straight angle

During a geometry class, Daniel was asked to draw a part of a line that starts from a point and extends infinitely in one direction. What is this called?

• Line segment

• Ray

• Line

• Vector

Elijah and Lily are standing on a street corner. Charlotte is walking towards them from a different street. If the streets are perpendicular, what angle does Charlotte make with Elijah and Lily when she reaches the corner?

• They form a 45-degree angle

• They form a 90-degree angle

• They are parallel

• They never touch each other

Benjamin, Charlotte, and Abigail are playing a game of darts. The dartboard is circular, and Benjamin throws a dart that passes through the center of the dartboard and ends up on the edge of the circle. What is the name of the line segment that represents Benjamin's throw?

• Radius

• Diameter

• Chord

• Arc

Benjamin and Isla are working on a project to design a straight path in their school garden. They are planning to place two angles in the path that add up to 180 degrees. What should these angles be called?

• Complementary angles

• Supplementary angles

• Adjacent angles

• Vertical angles

Elijah, Aiden, and Abigail are playing a game of drawing. Elijah drew a straight path that extends infinitely in both directions with no endpoints. What is the term for the path that Elijah drew?

• Ray

• Line segment

• Line

• Vector

Harper, Liam, and Aria were discussing about rays in their geometry class. Harper said that a ray can be measured. Aria disagreed. According to you, which of the following is not a characteristic of a ray?

• It has one endpoint

• It can be measured

• It extends infinitely in one direction

• It is part of a line
