About This Quiz

How well do you remember this branch of mathematics dealing with the relationships between points, lines, surfaces and more? Remember the basics with this geometry quiz now!

When two lines run equally side by side and never intersect, they are considered to be __________.

The grid street system contains many parallel streets that never intersect.

When two lines intersect and form right angles, they are said to be ________.

Two perpendicular lines form not only a right angle, but what is often referred to as a cross - similar to a T!

What is the amount of space occupied by a 3D object?

The volume is measured in cubic units. This refers to the number of little element cubes that fit inside the figure you are measuring.

This is a solid shape that is perfectly round, like a ball.

There are no faces, no edges and no vertices in a sphere.

What is a quadrilateral with four equal sides and four right angles?

To add more geometry to this answer: A square is always a rhombus, and all squares are considered rectangles.

What is the distance around a circle known as?

Just as there are subfields, there are also various branches of geometry. These include Euclidean, Spherical, Synthetic, Analytic, Finite, Projective, Differencial, Riemannian and Non-Euclidean.

Which type of angle is 90 degrees?

A right angle is a perfect 90 degrees. It makes a square in the corner.

This is a polygon with 3 sides and 3 angles...

There are several types of triangles in the world of geometry. They include right triangle, scalene triangle, isosceles triangle and acute triangle to name a few.

Which type of triangle has three equal sides?

Each angle of an equilateral triangle measures 60 degrees for a total of 180 degrees. No matter which way you turn the triangle, it will always look the same.

A polygon made with a continuous line which is always the same distance from the center is call a ... ?

A circle is a line that isn't straight.

What is the name for a two-dimensional object that has no endpoints and continues on forever in both directions?

The word geometry comes from the Ancient Greek for 'geo,' meaning 'earth,' and 'mentron,' meaning 'measurement'.

What is the name for part of a line that has one end point and goes on forever in another direction?

A mathematician who works in the field of geometry is known as a 'geometer.'

Two rays with the same end point make a(n) _______.

Geometry has many different subfields. These include Euclidean, differential, topology, convex, discrete and algebraic geometry.

Name the type of angle which measures more than 90 degrees.

Discrete geometry is the study of simple geometric objects such as points, lines and circles.

An ______ angle measures less than 90 degrees.

Algebraic geometry studies geometry through the use of multivariate polynomials and other algebraic techniques.

The point where two sides meet is called the _______.

The plural form of the word is either 'vertexes' or 'vertices.'

A polygon with four sides and four angles is called a _______.

Differential geometry uses techniques of calculus and linear algebra to study problems in geometry. It has applications in physics, including in general relativity.

When two of the three sides of a triangle are equal in length, it is called a(n) ______ triangle.

Topology, a subfield of geometry, is concerned with the properties of geometric objects that are unchanged by continuous mappings.

A _____ is a quadrilateral with one pair of parallel sides.

It is possible that a trapezoid has more than one pair of parallel sides. It just has to have AT LEAST one pair.

Similar to a square, this quadrilateral has four sides and four right angles, and its opposite sides are parallel...

A rectangle is very similar to a square, except that not all four sides are the same length. Two sides are one length, and the other two sides are a different length.

What is a parallelogram?

While all rectangles are parallelograms, not all parallelograms are necessarily rectangles because they don't always have right angles.

This is a parallelogram with four equal side and equal opposite angles...

Squares are a type of rhombus because they have congruent angles and two pairs of parallel sides.

What is the line enclosing a plane area?

Coaches must stand along the perimeter of the field while their players play the game.

This type of triangle has no two sides of equal length...

Euclidean geometry is named for the Alexandrian Greek mathematician, Euclid. He is often referred to as the 'father of geometry.'

What is the name of the tool used to measure angles?

A protractor is a geometric tool in the shape of a semicircular disk.

What is the name of a triangle that has two equal sides?

Fun fact: The three angles of a triangle will always add up to 180 degrees.

Plane figures with the same size and shape are known to be ________.

Congruent objects or congruent sides - they have the exact same length and shape.

The line of ________ divides two matching parts.

The line of symmetry can be vertical, horizontal, or diagonal.

Measured in units, the _____ is the size a surface takes up.

The area of a flat, or plane figure is the number of unit squares that can be contained within it.

The ________ is the length of a straight line through the center of a circle.

If you want to split a cookie between two people, the diameter of the cookie is the line you want to use.

This point is equidistant from the ends of a line.

Either from the ends of a line, or the extremities of a particular figure, the midpoint will always be the 'middle."

When a triangle contains an obtuse angle within it, it is called a(n) _________ triangle.

An example of an obtuse triangle would be one having a 110 degree angle, a 25 degree angle, and a 45 degree angle - all adding up to 180 degrees.

This is a solid shape with a circular base and a curved surface that come to a point together.

To help you remember a cone, think of a construction site, a beach toy, or best of all, an ice cream cone.

Two angles whose sum is a right (90 degree) angle are called ________.

They complement each other well. An example of this would be a 40 degree angle and a 50 degree angle. They could also be 26 degrees and 64 degrees.

This solid shape has one curved surface and two congruent circular bases. What is it called?

A cylinder can have either 2 or 3 faces, 0 or 2 edges, but it can have no vertices.
