A polygon is a flat, closed plane
shape made up of three or more
line segments called sides
TRUE OR FALSE:
A QUADRILATERAL IS A
POLYGON WITH TWO SIDES
A QUADRILATERAL IS A
POLYGON WITH FOUR SIDES
A SIX SIDED SHAPE IS
CALLED A _________?
WHAT ARE THE NAME
FOR QUADRILATERALS
WITH FOUR EQUAL
SIDES?
A SQUARE AND A RHOMBUS!!

Area is measured in
square units.
Area is the measure of the number
of square units inside a figure.
Perimeter is the measure of the
distance around a shape.
A line is a straight path that
extends in two directions.
Do Perpendicular Lines
Interest at:
• RIGHT ANGLES
• ACUTE ANGLES
• OBTUSE ANGLES
When perpendicular lines intersect, they
create right angles.

Which is an example of parallel
lines?

Since B is the middle letter in the angle name,
<ABC, B has to be the vertex of the angle.
Which direction would ray MB need
to be moved to make an obtuse
angle?
B
M
R
Ray MB would need to be
moved to the left, to make an
obtuse angle because an
obtuse angle is greater than
90 degrees.

Congruent figures are the
same shape, but can be
different sizes?
Congruent figures are the same
shape AND size.
If two figures are similar, are they
A: The same shape, but different
sizes?
B: Different shapes, but the
same size?
A: The same shape, but not necessarily
the same size.
Similar figures have to be the same
shape, however, they can be the same or
different sizes.
Are these figures:
•Congruent
•Similar but not congruent
•Neither
The figures are similar because they
are the same shape, but not the
same size.
Do all figures have a line or
lines of symmetry?
All figures do not have a line of symmetry.
Has line of
symmetry
Does not have
symmetry
What is another name for a line
of symmetry?
A: A curved line
B: A diagonal line
C: A perfect line
D: A fold line
Another name for a line of
symmetry is a FOLD LINE!
A line of symmetry separates a figure into
two parts that math exactly. You can FOLD
a shape along the line(s) of symmetry and
the pieces will lay directly on top of another.
How many lines of symmetry
does this figure have?
A: One
B: Three
C: Four
D: Five
Which triangle is an
equilateral triangle?
A
B
C
A scalene triangle has three
sides and angles that are
equal?
Letter A: Is an equilateral
triangle
An equilateral
triangle has
three sides and
angles that are
equal.
FALSE!!!!!
A scalene triangle has NO sides or
angles that are equal.
An equilateral triangle has three
sides and angles that are equal.
SCALENE

Another name for a
translation is a “step”
Another name for a translation is a
SLIDE!!
A translation is when you move a figure
up, down, or over.
WHICH IS AN EXAMPLE
OF A REFLECTION:
A
B
C
A:
A reflection is when you FLIP an object
over a line. Think of the object looking
“opposite” or think of a “mirror effect.”

This figure is made of 3 squares
together. What is the area of this
figure in square inches?
B
27 square inches (27 in²)
3 x 3 = 9 square
inches
Add both the rectangle &
square to get the area of the
entire figure:
9 square inches
+ 18 square inches
27 square inches
6 x 3 = 18 square inches
Bob wants to cover his square garden
with mulch to protect the plants. Bags
come in sizes that are measured in
square feet. What size bag will Bob need
to exactly cover the entire garden area?
