Do you remember? Line segment Endpoint Line Horizontal Vertical Parallel Perpendicular Triangle Quadrilateral Opposite Adjacent Parallelogram Rhombus Rectangle Square Perimeter Centimeter

Line segment A part of a line; A line segment has two endpoints

Endpoint The point at either end of a line segment

Line A straight path that goes on forever in opposite directions What are some types of lines? Horizontal Vertical Parallel Perpindicular

Horizontal lines Lines that extend in two directions, left and right. What is the opposite of horizontal? Vertical

Vertical lines Lines that extend in two directions, up and down

Parallel lines Two lines that are the same distance apart everywhere What is the opposite of parallel? Perpendicular

Perpendicular lines Two lines that cross to form right angles

Triangle A polygon with three sides What is a polygon with four sides called? A quadrilateral

Quadrilateral A polygon with 4 sides What are some types of quadrilaterals? Parallelograms Trapezoids Squares Rectangles Rhombuses

Opposite sides Sides that are across from each other; they do not meet at a point Example: Sides A and B are opposite of each other Would sides A and D be opposite of each other? No What would sides A and D be? Adjacent to each other A B C D

Adjacent sides Two sides that meet at a point Example: Sides A and D are adjacent to each other Are sides A and B opposite or adjacent? Opposite A B CD

Parallelogram A quadrilateral with both pairs of opposite sides parallel What are some examples of parallelograms? Rhombus Square Rectangle

Rhombus A parallelogram with congruent sides

Rectangle A parallelogram that has all right angles

Square A parallelogram with 4 congruent sides and 4 right angles A square is both a rhombus and a rectangle
