Lines, Line segments, or rays that never cross or meet
What is parallel?
100
A polygon that has four angles and four sides
What is a quadrangle or quadrilateral?
100
The set of all points in space that are the same distance from a fixed point. The fixed point is the center.
What is a sphere?
100
The distance around a 2-D shape, along the boundary of the shape
What is perimeter?
100
A closed 2-D figure that is NOT a polygon
What is a circle?
200
An angle that is exactly 90 degrees
What is a right angle?
200
A quadrilateral with two pairs of parallel sides. Opposite sides are congruent. Opposite angles have the same measure
What is a parallelogram?
200
A 3-D shape that has two circular bases that are parallel and congruent and are connected by a curved surface.
What is a cylinder?
200
The angles of this shape total 180 degrees.
What is a triangle?
200
This divides a figure into two parts that are mirror images of each other
What is a line of symmetry?
300
Intersecting lines that cross or meet at a right angle.
What are perpendicular lines?
300
A quadrilateral that has exactly one pair of parallell sides
What is a trapezoid?
300
This shape has 12 edges, 8 vertices, and 6 faces.
What is a cube?
300
The amount of surface inside a closed boundary measured in square units
What is area?
300
Having the same shape and size
What is congruent?
400
An angle that is larger than 0 degrees and less than 90 degrees
What is an acute angle?
400
This shape has 3 sides, 3 angles, and one angle is 90 degrees.
What is a right triangle?
400
A 3-D shape with one base of any polygon shape and all other faces are triangles. The faces come together at a vertex.
What is a pyramid?
400
If one side of an equilateral triangle measures 5 cm, what is the measurement of the other two sides? What is the perimeter of this shape?
What is 5 cm for each side? (all sides of an equilateral triangle are the same length)
What is 15 cm for the perimeter? (5x3)
400
Moving a figure by flipping it over a line
What is reflection?
500
A straight path that starts at one point (endpoint) and continues forever in one direction
What is a ray?
500
This is the shape of a stop sign.
What is an regular octagon? It has eight equal sides and therefore is regular a polygon.
500
A 3-D shape with two parallel bases that are the same size and shape. All other faces are parallellograms and connect the bases. Its name comes from the shape of its base.
What is a prism?
500
The measurement of an obtuse angle
What is greater than 90 degrees and less than 180 degrees?
500
Two numbers that are used to locate a point on a coordinate grid, often written as (x,y) where x is the horizontal position and y is the vertical position
