Geometric Terms
point
A pair of lines that never intersect
Parallel lines
A figure can have more than one line of symmetry. True or False?
True
A shape that has opposite sides parallel and opposite sides the same length.
Parallelogram
Which figure could you drwa that fits the clue? The figure is NOT always a rectangle, but is a quadrilateral.
A. Square
B. Triangle
C. Hexagon
D. Parallelogram
D. Parallelogram
Line
A pair of lines that pass through the same point.
Intersecting Lines
Which of the following numbers has exactly 2 lines of symmetry?
A. 1
B. 3
C. 7
D. 8
D. 8
A shape that has four square angles or square corners, but does not have all equal sides.
Rectangle
Which figure could you draw that fits the clue? The figure can be sorted into a group of parallelograms or a group of rhombi.
A. Square
B. Rectangle
C. Trapezoid
D. Hexagon
A. Square
A part of a line that has two endpoints.
Line segment
A pair of lines that intersect to form square angles.
Perpendicular lines
How many lines of symmetry does a block letter T have?
2
A shape that has all sides the same length and does not have square angles.
Rhombus
Draw a quadrilateral that is NOT a rectangle, a rhombus, or a square.
Students drawing should be a trapezoid.
Ray
Draw the following geometric term on your white board. PERPENDICULAR LINES
Students drawing should include 2 lines that intersect to form square angles.
How many lines of symmetry does a square have?
4
A shape that has four square angles and all sides the same length.
What are two other terms you can use to describe a rectangle?
Quadrilateral and Parallelogram
Draw the following geometric term. LINE SEGMENT
Students drawing should include a line with a point at each end.
If all perpendicular lines are also intersecting lines, are all intersecting lines also perpendicular lines? Explain!
No, (Sample Answer: Perpendicular lines meet at a square angles. Not all intersecting lines do.)
How can you tell when a line is NOT a line of symmetry?
A shape that as at least one pair of parallel sides.
Trapezoid
What is the term that does not describe a square?
Quadrilateral, Parallelogram, Pentagon, Rectangle, Rhombus, Polygon
Pentagon
