Lines
A part of a line with two endpoints is called this.
line segment
This is the number of angles a quadrilateral has.
4
This has four right angles, four equal sides, and two pairs of parallel sides.
a square
This is a polygon with three sides and three angles.
a triangle
These are two lines that will never intersect.
parallel lines
This type of angle measures 90 degrees, which forms the perfect square corner.
right angle
A square can be called this even though this can have only 2 pairs of equal sides instead of 4 equal sides.
a rectangle
True or False...A circle is a polygon.
FALSE. Circles are not made up of line segments.
Any pair of lines that cross or any pair of sides that meet are this.
intersecting lines
When two rays meet at their endpoints and form an angle that measures less than a right angle, it is called this.
acute angle
This quadrilateral has only exactly one pair of parallel sides.
a trapezoid
This is a polygon with four sides and four angles.
a quadrilateral
These are intersecting lines that form right angles.
perpendicular lines
This is the number of angles that 2 hexagons have.
12
Rectangles, rhombuses, and squares all belong to this group of quadrilateral that have 2 pairs of parallel sides and 2 pairs of equal sides.
parallelograms
True or False...A cube is a polygon.
FALSE A cube is a 3-dimensional shape. Polygons are 2-dimensional (plane shapes).
This is the number of pairs of parallel sides a regular octagon has.
4
half of a line
a ray
These are the two names for a triangle with no equal sides and one obtuse angle.
two answers
scalene triangle and an obtuse triangle
In this quadrilateral you can find 4 pairs of perpendicular sides, 2 pairs of sides that will never cross, and 2 pairs of equal sides.
a rectangle (4 right angles, 2 pairs of parallel sides)
This is a ten sided polygon.
