Drawing Two-Dimensional Figures
Note to Families
When studying geometry, it is important to understand and be able to use precise language for describing and comparing shapes. In this assignment, students illustrate certain terms and use their understanding of geometry words to draw shapes with different combinations of attributes. We include the vocabulary guide below to refresh your memory and help students remember what the words mean.
Question 1.
Draw at least two examples of each term below. If you can’t remember what the words mean, look at the guide to geometry terms on page 95.
a.
Answer:
A lines which are at a similar distance is calle da parallel lines .The examples for such lines are as shown below.
b.
Answer:
Two lines which intersect at a point of 90 degrees is called perpedicular lies with two examples as shown below.
c.
Answer:
The angle which precisely measures at an angle of 90 degrees is called Right angle with two examples as shown below.
d.
Answer:
The angle which is higher than 90 degrees is called a obtuse angles with two examples as shown in the below figure.
e.
Answer:
The angle which is lesser than 90 degrees is called a acute angles with two examples as shown in the below figure.
Question 2.
Draw at least one shape that matches each description below. For each shape, use arrows and words to show how your shape matches the description.
ex:
a.
Answer:
A Quadrilateral is drawn with just a single pair of parallel sides as shown in the below table.
b.
Answer:
A Pentagon contains 5 sides and exactly with a single right angle and a single acute angle are drawn as shown below.
c.
Answer:
As the name itself indicates hexa means six sides with Exactly single pair of perpendicular sides are as shown below.
d.
Answer:
A hexagon with a single pair of parallel sides are sa shown below.

Symmetry
Question 1.
Figures a—c show only half of the designs, on the left side of their lines of symmetry. Complete each design on the right side of the line of symmetry.
ex:
a.
Answer:
For the given Figure, the design on the right side of the Line of the Symmetry is Drawn as shwon below.
b.
Answer:
For the given Figure, the design on the right side of the Line of the Symmetry is Drawn as shwon below.
c.
Answer:
For the given Figure, the design on the right side of the Line of the Symmetry is Drawn as shwon below.
Question 2.
What did you do to make sure that the other half of each design you drew was accurate?
Answer:
I think both the sides of each design was accurate.
Question 3.
Preston says that when a figure has a line of symmetry, the halves on both sides are congruent (exactly the same size and shape). Do you agree or disagree with him? Explain your answer.
Answer:
Yes ofcourse , What Preston said is Exactly correct and I agree Because when an imaginary Line is Drawn in the middle of figure , it is called a Line of Symmetry and both the halves are congruent.
Question 4.
Tasha says that this shape has 4 lines of symmetry. Do you agree or disagree with her? Explain your answer and be sure to draw in any lines of symmetry you can find. (Hint: Trace the figure, cut it out, and fold it before you make your decision.)
Answer:
I disagree with Tasha since it is impossible to have the given Shape Parallelogram with 4 Lines of Symmetry. Because there is no chance of buiding the line go through the middle of the shape and split half of Shape.
Question 5.
CHALLENGE Find a picture in the newspaper, in a magazine, or on the computer that has exactly two lines of symmetry. Attach the picture, and then draw in its lines of symmetry. Explain how you would convince someone that it has exactly two lines of symmetry.
Answer:
I took a picture of a computer and two imaginary imaginary Lines are drawn from the center point of view.Then we can see the Line of Symmetry as shown below.

Classifying & Drawing Quadrilaterals
A quadrilateral is any polygon that has 4 sides. There are many kinds of quadrilaterals, including these:
Trapezoid: a quadrilateral with exactly 1 pair of parallel sides
Rectangle: a quadrilateral with 2 pairs of parallel sides and 4 right angles
Rhombus: a quadrilateral with 4 sides that are all the same length
Square: a quadrilateral with 4 right angles and 4 sides that are all the same length
Parallelogram: a quadrilateral with 2 pairs of parallel sides
Question 1.
Look carefully at the figures below. Decide how many right angles, pairs of congruent sides, and pairs of parallel sides each has. Then circle the word or words that say what kind of figure it is. You might circle more than one word for some figures.
a.
Answer:
The given shape Rhombus is circled and the number of Right angles, Pair of parallel sides and pair of congruent sides are wriiten in the given table as shown below.
b.
Answer:
The given shape trapezoid is circled and the number of Right angles, Pair of parallel sides and pair of congruent sides are wriiten in the given table as shown below.
c.
Answer:
The given shape parallelogram is circled and the number of Right angles, Pair of parallel sides and pair of congruent sides are wriiten in the given table as shown below.
Question 2.
Start with the same line each time to draw the different shapes named below.
ex: square
a. Parallelogram that is not a rhombus
Answer:
A parallelogram which is not a Rhombus is drawn with the shape as shown below.
b. Trapezoid
Answer:
A trapezoid with the same Line is drawn which is as shown below.
c. Rectangle that is not a square
Answer:
A Rectangle that is not a Square is nothing but the rhombus which is as shwon below.
Question 3.
CHALLENGE Which of your shapes above has the largest area? How can you tell?
Answer:
From the above three given figures third one is the largest area.Since it filled in three boxes of space.
