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!! SQUARE RHOMBUS

NAME THE GEOMETRIC FIGURE EACH SIGN REPRESENTS:

Octagon Rectangle Triangle

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. Right Angle

Which is an example of parallel lines? A: B: C:

B: Parallel lines do not intersect

If given the name <ABC, which angle is correct? A B C A: B: A C B C: A C B

A: B A C 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. M B R B M R

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? ABC

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 EQUILATERAL

The Answer is B: FIVE

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 BC

A reflection is when you FLIP an object over a line. Think of the object looking “opposite” or think of a “mirror effect.” A:

The Perimeter of this figure

26 units 7 units 6 units 7 units To find perimeter, you have to add all the sides (around the figure)

This figure is made of 3 squares together. What is the area of this figure in square inches? B

27 square inches (27 in²) 6 x 3 = 18 square inches 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

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?

144 square feet

Find the Area (in square units) and Perimeter of this figure

Area = 74 square units Perimeter = 42 units
