Describing Shapes
Something that you can use to describe an object, like its color, size, or number or sides
What is an attribute?
A closed plane shape with straight sides that are line segments.
What is a polygon?
This is an angle that forms a square corner and is designated by a square that marks the angle.
What is a right angle?
This is what they call lines that are in the same plane that never cross or touch each other and are always the same distance apart.
What are parallel lines?
What is a quadrilateral?
A shape that begins and ends at the same point.
What is a closed shape?
What is a side?
This type of angle measures less than 90 degrees.
What is an acute angle?
This 2 dimensional closed polygon has exactly 4 straight sides, 4 vertices, and four angles that add up to 360 degrees.
What is a quadrilateral?
This is a four sided polygon with at least one pair of parallel sides (bases) and can be categorized into types such as isosceles, right, and scalene.
What are trapezoids?
A shape that does not begin and end at the same point.
What is an open shape?
This attribute of plane shapes is formed by two line segments that share an endpoint.
What are angles?
This type of angle measures 90 degrees.
What is a right angle?
This type of quadrilateral is also a parallelogram that is often described as a diamond. It has four sides of equal length, with opposite sides that are parallel and opposite angles that are of equal measure (congruent).
What is a rhombus?
This four sided polygon has two pairs of parallel and opposite sides that are equal in length and can include rectangles, rhombuses, squares, and rhomboids.
What are parallelograms?
A shape on a flat surface that is formed by curved paths, line segments, or both.
What is a plane shape?
This point is where two line segments meet and connect to form an angle.
vertex
This type of angle measures greater than 90 degrees.
What is an obtuse angle?
These types of lines intersect at right angles , forming a T shape.
What are perpendicular lines?
This four sided polygon consists of four right angles, with opposite sides that are parallel and equal in length. Some types of these include rectangles and squares.
A part of a line that is straight and has two endpoints.
What is a line segment?
Each polygon is made up of these two things.
What are angles and vertices.
True or false.
It is possible for a polygon to have an angle greater than 90 degrees AND an angle that is less than 90 degrees.
True
This term is used to express figures that are identical in both shape and size, meaning their corresponding sides and angles are equal.
What is congruent?
This type of polygon is also a quadrilateral with four equal sides, four right angles, and two sets of parallel opposite sides.
What is a square?
